Search for Higgs boson decays into a Z boson and a light hadronically decaying resonance in pp collisions at s =13 TeV with the ATLAS detector
No full textA search for decays of the Higgs boson into a boson and a light resonance, with a mass of 0.5-3.5 GeV, is performed using the full 140 fb dataset of 13 TeV proton-proton collisions recorded by the ATLAS detector during Run 2 of the LHC. Leptonic decays of the boson and hadronic decays of the light resonance are considered. The resonance can be interpreted as a or meson, an axion-like particle, or a light pseudoscalar in two-Higgs-doublet models. Due to its low mass, it would be produced with high boost and reconstructed as a single small-radius jet of hadrons. A neural network is used to correct the Monte Carlo simulation of the background in a data-driven way. Two additional neural networks are used to distinguish signal from background. A binned profile-likelihood fit is performed on the final-state invariant mass distribution. No significant excess of events relative to the expected background is observed, and upper limits at 95% confidence level are set on the Higgs boson's branching fraction to a boson and a light resonance. The exclusion limit is ~10% for the lower masses, and increases for higher masses. Upper limits on the effective coupling of an axion-like particle to a Higgs boson and boson are also set at 95% confidence level, and range from 0.9 to 2 TeV
Azimuthal anisotropies of charged particles with high transverse momentum in Pb + Pb collisions at s NN = 5.02 TeV with the ATLAS detector
No full textA measurement is presented of elliptic ( v 2 ) and triangular ( v 3 ) azimuthal anisotropy coefficients for charged particles produced in Pb + Pb collisions at s NN = 5.02 TeV using a dataset corresponding to an integrated luminosity of 0.44 nb − 1 collected with the ATLAS detector at the LHC in 2018. The values of v 2 and v 3 are measured for charged particles over a wide range of transverse momentum ( p T ), 1–400 GeV , and Pb + Pb collision centrality, 0–60%, using the scalar-product and multiparticle cumulant methods. These methods are sensitive to event-by-event fluctuations and nonflow effects in the measurements of azimuthal anisotropies. Positive values of v 2 are observed up to a p T of approximately 100 GeV from both methods across all centrality intervals. Positive values of v 3 are observed up to approximately 25 GeV using both methods, though the application of the three-subevent technique to the multiparticle cumulant method leads to significant changes at the highest p T . At high p T ( p T ⪆ 10 GeV ), charged particles are dominantly from jet fragmentation. These jets, and hence the measurements presented here, are sensitive to the path-length dependence of parton energy loss in the quark-gluon plasma produced in Pb + Pb collisions.Agence Nationale de la

Charged-hadron and identified-hadron ( K S 0 , Λ , Ξ − ) yield measurements in photonuclear Pb + Pb and p + Pb collisions at s N N = 5.02 TeV with ATLAS
No full textThis paper presents the measurement of charged-hadron and identified-hadron ( K S 0 , Λ , Ξ − ) yields in photonuclear collisions using 1.7 nb − 1 of s N N = 5.02 TeV Pb + Pb data collected in 2018 with the ATLAS detector at the Large Hadron Collider. Candidate photonuclear events are selected using a combination of tracking and calorimeter information, including the zero-degree calorimeter. The yields as a function of transverse momentum and rapidity are measured in these photonuclear collisions as a function of charged-particle multiplicity. These photonuclear results are compared with 0.1 nb − 1 of s N N = 5.02 TeV p + Pb data collected in 2016 by ATLAS using similar charged-particle multiplicity selections. These photonuclear measurements shed light on potential quark-gluon plasma formation in photonuclear collisions via observables sensitive to radial flow, enhanced baryon-to-meson ratios, and strangeness enhancement. The results are also compared with the Monte Carlo generator and hydrodynamic calculations to test whether such photonuclear collisions may produce small droplets of quark-gluon plasma that flow collectively.Agencia Nacional de Promoción Científica y Tecnológica http://dx.doi.org/10.13039/501100003074Australian Research Council http://dx.doi.org/10.13039/501100000923Bundesministerium für

Search for displaced leptons in s = 13 TeV and 13.6 TeV p p collisions with the ATLAS detector
No full textA search for leptons displaced from the primary vertex is performed with the ATLAS detector at the Large Hadron Collider. The search includes the full proton-proton collision dataset collected during Run 2 at s = 13 TeV and a partial dataset collected during Run 3 in 2022–2023 at s = 13.6 TeV , corresponding to integrated luminosities of 140 fb − 1 and 56.3 fb − 1 , respectively. Final states with displaced electrons or muons are considered, and novel triggers introduced in Run 3 are employed that use large impact parameter tracking to reconstruct displaced tracks with low momentum. In addition, photon reconstruction and multivariate techniques are employed to broaden the sensitivity to channels with large background rates or highly displaced electrons, respectively. The results are consistent with the Standard Model background expectations and are used to set model-independent limits on the production of displaced electrons and muons. The analysis is also interpreted in the context of a gauge-mediated supersymmetry breaking model with pair-produced long-lived sleptons and a dark sector model with pair-produced chargino-like states. The results include 95% confidence level exclusions of selectrons with lifetimes from 4 ps to 60 ns and a mass of 150 GeV, and exclusions of selectrons, smuons, and staus with a lifetime of 0.3 ns for masses up to 740, 830, and 440 GeV, respectively. Dark charginos with masses up to 380 GeV are excluded for a mass difference with the neutral state of 40 GeV, and mass differences down to 17 GeV are excluded for dark charginos with a 100 GeV mass.CERN http://dx.doi.org/10.13039/100012470TRIUMF http://dx.doi.org/10.13039/100012419Simon Fraser University http://dx.doi.org/10.13039/501100004326Institut National de Physique Nucléaire et de

Search for cascade decays of charged sleptons and sneutrinos in final states with three leptons and missing transverse momentum in p p collisions at s = 13 TeV with the ATLAS detector
No full textA search for cascade decays of charged sleptons and sneutrinos using final states characterized by three leptons (electrons or muons) and missing transverse momentum is presented. The analysis is based on a dataset with 140 fb − 1 of proton-proton () collisions at a center-of-mass energy of s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. This paper focuses on a supersymmetric scenario that is motivated by the muon anomalous magnetic moment observation, dark-mattter relic density abundance, and electroweak naturalness. A mass spectrum involving light Higgsinos and heavier sleptons with a bino at intermediate mass is targeted. No significant deviation from the Standard Model expectation is observed. This search enables us to place stringent constraints on this model, excluding at the 95% confidence level charged slepton and sneutrino masses up to 450 GeV when assuming a lightest neutralino mass of 100 GeV and mass-degenerate selectrons, smuons and sneutrinos.CERN http://dx.doi.org/10.13039/100012470TRIUMF http://dx.doi.org/10.13039/100012419Simon Fraser University

The UmuC subunit of the E. coli DNA polymerase V shows a unique interaction with the β-clamp processivity factor
No full textBackground
Strict regulation of replisome components is essential to ensure the accurate transmission of the genome to the next generation. The sliding clamp processivity factors play a central role in this regulation, interacting with both DNA polymerases and multiple DNA processing and repair proteins. Clamp binding partners share a common peptide binding motif, the nature of which is essentially conserved from phage through to humans. Given the degree of conservation of these motifs, much research effort has focussed on understanding how the temporal and spatial regulation of multiple clamp binding partners is managed. The bacterial sliding clamps have come under scrutiny as potential targets for rational drug design and comprehensive understanding of the structural basis of their interactions is crucial for success.
Results
In this study we describe the crystal structure of a complex of the E. coli β-clamp with a 12-mer peptide from the UmuC protein. UmuC is the catalytic subunit of the translesion DNA polymerase, Pol V (UmuD’2C). Due to its potentially mutagenic action, Pol V is tightly regulated in the cell to limit access to the replication fork. Atypically for the translesion polymerases, both bacterial and eukaryotic, Pol V is heterotrimeric and its β-clamp binding motif (357 QLNLF 361) is internal to the protein, rather than at the more usual C-terminal position. Our structure shows that the UmuC peptide follows the overall disposition of previously characterised structures with respect to the highly conserved glutamine residue. Despite good agreement with the consensus β-clamp binding motif, distinct variation is shown within the hydrophobic binding pocket. While UmuC Leu-360 interacts as noted in other structures, Phe-361 does not penetrate the pocket at all, sitting above the surface.
Conclusion
Although the β-clamp binding motif of UmuC conforms to the consensus sequence, variation in its mode of clamp binding is observed compared to related structures, presumably dictated by the proximal aspartate residues that act as linker to the poorly characterised, unique C-terminal domain of UmuC. Additionally, interactions between Asn-359 of UmuC and Arg-152 on the clamp surface may compensate for the reduced interaction of Phe-361
Evidence for the Collective Nature of Radial Flow in Pb + Pb Collisions with the ATLAS Detector
No full textAnisotropic flow and radial flow are two key probes of the expansion dynamics and properties of the quark-gluon plasma (QGP). While anisotropic flow has been extensively studied, radial flow, which governs the system’s radial expansion, has received less attention. Notably, direct experimental evidence for the global and collective nature of radial flow fluctuations has been lacking. This Letter presents the first measurement of transverse momentum ( p T ) dependence of radial flow fluctuations ( v 0 ( p T ) ) over 0.5 < p T < 10 GeV and demonstrates its collective nature using a two-particle correlation method in Pb + Pb collisions at s NN = 5.02 TeV . The data reveal three key features supporting the collective nature of radial flow: long-range correlation in pseudorapidity, factorization in p T , and centrality-independent shape in p T . The comparison with a hydrodynamic model demonstrates the sensitivity of v 0 ( p T ) to bulk viscosity, a crucial transport property of the QGP. These findings establish a new, powerful tool for probing collective dynamics and properties of the QGP.CERN http://dx.doi.org/10.13039/100012470TRIUMF http://dx.doi.org/10.13039/100012419Institut

Search for the jet-induced diffusion wake in the quark-gluon plasma via measurements of jet-track correlations in photon-jet events in Pb + Pb collisions at s N N = 5.02 TeV with the ATLAS detector
No full textThis paper presents a measurement of jet-track correlations in photon-jet events, using 1.72 nb − 1 of Pb + Pb data at s N N = 5.02 TeV recorded with the ATLAS detector at the LHC. Events with energetic photon-jet pairs are selected, where the photon and jet are approximately back-to-back in azimuth. The angular correlation between jets and charged-particle tracks with transverse momentum ( p T ) in the range 0.5–2.0 GeV in the hemisphere opposite to the jet, | Δ ϕ (jet,track) | > π / 2 , is measured as a function of their relative pseudorapidity difference, | Δ η (jet,track) | . In central Pb + Pb collisions, these correlations are predicted to be sensitive to the diffusion wake in the quark-gluon plasma resulting from the lost energy of high- p T partons traversing the plasma, with a characteristic modification as a function of | Δ η (jet,track) | . The correlations are examined with different selections on the jet-to-photon p T ratio to select events with different degrees of energy loss. No diffusion wake signal is observed within the current sensitivity and upper limits at 95% confidence level on the diffusion wake amplitude are reported.TRIUMF

Measurement of Higgs boson decay into b-quarks in associated production with a top-quark pair in pp collisions at s = 13 TeV with the ATLAS detector
No full textAbstract The associated production of a Higgs boson and a top-quark pair is measured in events characterised by the presence of one or two electrons or muons. The Higgs boson decay into a b-quark pair is used. The analysed data, corresponding to an integrated luminosity of 139 fb−1, were collected in proton-proton collisions at the Large Hadron Collider between 2015 and 2018 at a centre-of-mass energy of s 1436019 \sqrt{s} 1436019 = 13 TeV. The measured signal strength, defined as the ratio of the measured signal yield to that predicted by the Standard Model, is 0.35 − 0.34 + 0.36 1436019 {0.35}_{-0.34}^{+0.36} 1436019 . This result is compatible with the Standard Model prediction and corresponds to an observed (expected) significance of 1.0 (2.7) standard deviations. The signal strength is also measured differentially in bins of the Higgs boson transverse momentum in the simplified template cross-section framework, including a bin for specially selected boosted Higgs bosons with transverse momentum above 300 GeV
