Exploring nuclear structure with multiparticle azimuthal correlations at the LHC
No full textDetails of the nuclear structure of Xe-129, such as the quadrupole deformation and the nuclear diffuseness, are studied by extensive measurements of anisotropic-flow-related observables in Xe-Xe collisions at a centre-of-mass energy per nucleon pair root S-NN = 5.44 TeV with the ALICE detector at the LHC. The results are compared with those from Pb-Pb collisions at root S-NN = 5.02 TeV for a baseline, given that the Pb-208 nucleus exhibits a very weak deformation. Furthermore, comprehensive comparisons are performed with a state-of-the-art hybrid model using IP-Glasma+MUSIC+UrQMD. It is found that among various IP-Glasma+MUSIC+UrQMD calculations with different values of nuclear parameters, the one using a nuclear diffuseness parameter of a(0) = 0.492 and a nuclear quadrupole deformation parameter of beta(2) = 0.207 provides a better description of the presented flow measurements. These studies represent the first systematic exploration of nuclear structure at TeV energies, utilizing a comprehensive set of anisotropic flow observables. The measurements serve as a critical experimental benchmark for rigorously testing the interplay between nuclear structure inputs and heavy-ion theoretical models

No full textThe production cross sections of Bs0 and B+ mesons are reported in proton-proton (pp) collisions recorded by the CMS experiment at the CERN LHC with a center-of-mass energy of 5.02 TeV. The data sample corresponds to an integrated luminosity of 302 pb−1. The cross sections are based on measurements of the Bs0→ J/ψ(μ+μ−)ϕ(1020)(K+K−) and B+→ J/ψ(μ+μ−)K+ decay channels. Results are presented in the transverse momentum (pT) range 7–50 GeV/c and the rapidity interval |y| 10 GeV/c, both mesons are found to be suppressed in PbPb collisions (with RAA values significantly below unity), with less suppression observed for the Bs0 mesons. In this pT range, the RAA values for the B+ mesons are consistent with those for inclusive charged hadrons and D0 mesons. Below 10 GeV/c, both B+ and Bs0 are found to be less suppressed than either inclusive charged hadrons or D0 mesons, with the Bs0RAA value consistent with unity. The RAA values found for the B+ and Bs0 are compared to theoretical calculations, providing constraints on the mechanism of bottom quark energy loss and hadronization in the quark-gluon plasma, the hot and dense matter created in ultrarelativistic heavy ion collisions
