A search for resonances decaying into a Higgs boson and a new particle X in the XH → qqbb final state with the ATLAS detector
No full textA search for heavy resonances decaying into a Higgs boson (H) and a new particle (X) is reported, utilizing 36.1 fb−1 of proton–proton collision data at s=13TeV collected during 2015 and 2016 with the ATLAS detector at the CERN Large Hadron Collider. The particle X is assumed to decay to a pair of light quarks, and the fully hadronic final state XH→qq¯′bb¯ is analysed. The search considers the regime of high XH resonance masses, where the X and H bosons are both highly Lorentz-boosted and are each reconstructed using a single jet with large radius parameter. A two-dimensional phase space of XH mass versus X mass is scanned for evidence of a signal, over a range of XH resonance mass values between 1 TeV and 4 TeV, and for X particles with masses from 50 GeV to 1000 GeV. All search results are consistent with the expectations for the background due to Standard Model processes, and 95% CL upper limits are set, as a function of XH and X masses, on the production cross-section of the XH→qq¯′bb¯ resonance. © 2018 The Author(s)WosScopu

Uniquely factorizable entire functions
No full textAbstractLet f(z) be a transcendental entire function and n ⩾ 3 a prime number. Then (f(w) − aw) ∘ zn and ((w − a) f(w)) ∘ zn are uniquely factorizable (UF) for each complex number a, except for a countable set. Furthermore, if f(z) is prime and f(z) has infinitely many zeros such that almost all zeros are in ¦arg z − π¦ < ω (0 < ω < 12π), then fn is UF

Phys., 113, 5736 (2000) H.-S. Lee, A. B. McCoy, R. R. Toczylowski and S. M. Cyblulski, J. Chem. Phys., 113, 9549 (2000)Author Institution: Department of Chemistry, The Ohio State University; James Franck Institute, University of ChicagoThe rotational and spin-orbit predissociation dynamics of complexes is investigated theoretically using the stabilization method of Mandelshtam using ab initio potential surfaces to describe the The calculations show large variations in the lifetimes of the complexes within narrow ranges of energy. In particular, we found a strong dependence of the lifetime on the parity of the state and the projection of the angular momentum onto the internuclear axis. Comparisons with available experimental data are made and the results of this purely ab inito treatment are found to be in good agreement with the experimental resonance energies and lifetimes
Tetrel–Hydride Interaction between XH<sub>3</sub>F (X = C, Si, Ge, Sn) and HM (M = Li, Na, BeH, MgH)
No full textA tetrel–hydride
interaction was predicted and characterized
in the complexes of XH<sub>3</sub>F···HM (X = C, Si,
Ge, Sn; M = Li, Na, BeH, MgH) at the MP2/aug-cc-pVTZ level, where
XH<sub>3</sub>F and HM are treated as the Lewis acid and base, respectively.
This new interaction was analyzed in terms of geometrical parameters,
interaction energies, and spectroscopic characteristics of the complexes.
The strength of the interaction is essentially related to the nature
of X and M groups, with both the larger atomic number of X and the
increased reactivity of M giving rise to a stronger tetrel–hydride
interaction. The tetrel–hydride interaction exhibits similar
substituent effects to that of dihydrogen bonds, where the electron-donating
CH<sub>3</sub> and Li groups in the metal hydride strengthen the binding
interactions. NBO analyses demonstrate that both BD<sub>H–M</sub> → BD*<sub>X–F</sub> and BD<sub>H–M</sub> →
BD*<sub>X–H</sub> orbital interactions play the stabilizing
role in the formation of the complex XH<sub>3</sub>F···HM
(X = C, Si, Ge, and Sn; M = Li, Na, BeH, and MgH). The major contribution
to the total interaction energy is electrostatic energy for all of
the complexes, even though the dispersion/polarization parts are nonnegligible
for the weak/strong tetrel–hydride interaction, respectively
CALCULATION OF THE TORSIONAL-ROTATIONAL ENERGY LEVELS OF AND
No full textAuthor Institution: Department of Physics, Texas Tech UniversityThe torsional-rotational energy levels of and have been calculated, where X is either O or S atoms, using an internal axis approach (IAM) for the asymmetric-asymmetric molecules. The internal axis transformation removes the large Coriolis interaction from and places it in the effective . However, this transformation introduces additional terms into that depend explicitly upon . Solution for the energy levels is considered at three stages. First, the solution of the transformed or effective in a free rotor basis. Second, inclusion of the rotational terms from (-independent). And third, inclusion of the terms from including the -dependent terms quadratic in the and the small -dependent terms from the residual Coriolis interaction. Results from the theoretical formulation and from numerical calculations for the above molecules will be presented
