Search for supersymmetry in events with at least one photon, missing transverse momentum, and large transverse event activity in proton-proton collisions at sqrt(s)=13 TeV

Albert M. Sirunyan, +2294 more
TL;DR: In this article, a search for physics beyond the standard model in final states with at least one photon, large transverse momentum imbalance, and large total transverse event activity is presented, and the data are interpreted in simplified models of gluino and squark pair production, in which gluinos or squarks decay via neutralinos to photons.
Journal ArticleDOI

Search for the decay of a Higgs boson in the ℓℓγ channel in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2359 more
TL;DR: In this paper, a search for a Higgs boson decaying into a pair of electrons or muons and a photon was described, and limits were set on the cross section for a standard model Higgs particle decaying to opposite-sign electron or muon pairs.
Journal ArticleDOI

Leptin and endocrine parameters in marathon runners.

TL;DR: An increased anabolic hormonal response in well trained marathon runners and hormonal reactions of increased stress in less trained runners are found, supporting the thesis of a linear relationship between physical fitness and leptin variations in the physiological range.
Journal ArticleDOI

Jet Shapes of Isolated Photon-Tagged Jets in Pb-Pb and pp Collisions at sNN =5.02 TeV

Albert M. Sirunyan, +2267 more
TL;DR: In central Pb-Pb events, a larger fraction of the jet momentum is observed at larger distances from the jet axis compared to pp, reflecting the interaction between the partonic medium created in heavy ion collisions and the traversing partons.
Journal ArticleDOI

Verification of precipitation from regional climate simulations and remote-sensing observations with respect to ground-based observations in the upper Danube catchment

TL;DR: In this paper, an evaluation of precipitation fields for four selected months simulated by the regional climate model At-moMM5 and provided by the satellite retrieval method AtmoSat is presented.
