TL;DR: In this article, the authors present searches for the Zγ decay of the Higgs boson and for narrow high-mass resonances decaying to Zγ, exploiting Z boson decays to pairs of electrons or muons.
Abstract: This article presents searches for the Zγ decay of the Higgs boson and for narrow high-mass resonances decaying to Zγ, exploiting Z boson decays to pairs of electrons or muons. The data analysis uses 36.1 fb−1 of pp collisions at √s=13 recorded by the ATLAS detector at the CERN Large Hadron Collider. The data are found to be consistent with the expected Standard Model background. The observed (expected — assuming Standard Model pp → H → Zγ production and decay) upper limit on the production cross section times the branching ratio for pp → H → Zγ is 6.6. (5.2) times the Standard Model prediction at the 95% confidence level for a Higgs boson mass of 125.09 GeV. In addition, upper limits are set on the production cross section times the branching ratio as a function of the mass of a narrow resonance between 250 GeV and 2.4 TeV, assuming spin-0 resonances produced via gluon-gluon fusion, and spin-2 resonances produced via gluon-gluon or quark-antiquark initial states. For high-mass spin-0 resonances, the observed (expected) limits vary between 88 fb (61 fb) and 2.8 fb (2.7 fb) for the mass range from 250 GeV to 2.4 TeV at the 95% confidence level.

TL;DR: In this article, the melting curves of aluminum, copper, and nickel are calculated on the basis of a quasiharmonic approximation, and the dependence of a phonon density of states on electron temperature is taken into account for both thermodynamic properties and a mean square displacement of atoms.
Abstract: We present melting curves of aluminum, copper, and nickel calculated on the basis of a quasiharmonic approximation. The dependence of a phonon density of states on electron temperature is taken into account for both thermodynamic properties and a mean square displacement of atoms. Linear expansion coefficients are strongly dependent on an approximation of the exchange-correlation functional; the generalized gradient approximation gives better results at normal conditions. Using the Lindemann criterion we obtain good agreement with experimental pressure dependences of the melting temperature for Al and Cu. In the case of Ni we consider a spin polarization effect to reproduce a recent first-principle simulation and shock-wave data. However, our melting curve is located significantly higher than static experimental points. We also consider a thermal excitation of electrons in a crystal and investigate the dependence of the melting temperature on the electronic one at normal and elevated densities. Hardening of the crystal structure for all the metals is obtained in our simulation; this effect might be confirmed experimentally owing to a relatively long lifetime of the two-temperature state.

TL;DR: In this article, the authors focus on the vertical distribution of SO2, considering mostly observations performed by instruments and techniques providing accurate vertical information, and the most noticeable feature of the vertical profile of the SO2 abundance in the Venus atmosphere is the presence of an inversion layer located at about 70-75 km, with VMRs increasing above.

TL;DR: In this paper, a data sample of events from proton-proton collisions with two isolated same-sign leptons, missing transverse momentum, and jets is studied in a search for signatures of new physics phenomena.
Abstract: A data sample of events from proton-proton collisions with two isolated same-sign leptons, missing transverse momentum, and jets is studied in a search for signatures of new physics phenomena by the CMS Collaboration at the LHC. The data correspond to an integrated luminosity of 35.9 inverse femtobarns, and a center-of-mass energy of 13 TeV. The properties of the events are consistent with expectations from standard model processes, and no excess yield is observed. Exclusion limits at 95% confidence level are set on cross sections for the pair production of gluinos, squarks, and same-sign top quarks, as well as top-quark associated production of a heavy scalar or pseudoscalar boson decaying to top quarks, and on the standard model production of events with four top quarks. The observed lower mass limits are as high as 1500 GeV for gluinos, 830 GeV for bottom squarks. The excluded mass range for heavy (pseudo)scalar bosons is 350-360 (350-410) GeV. Additionally, model-independent limits in several topological regions are provided, allowing for further interpretations of the results.
