Journal ArticleDOI

Measurement of inclusive jet production and nuclear modifications in pPb collisions at √sNN = 5.02 TeV

Vardan Khachatryan, +2262 more
- 04 Jul 2016 - 
TL;DR: In this paper, the jet transverse momentum spectra were studied in seven pseudorapidity intervals covering the range -2.0
Journal ArticleDOI

Search for third-generation leptoquarks and scalar bottom quarks in pp collisions at $ \sqrt{s}=7\;TeV $

S. Chatrchyan, +2257 more
- 01 Dec 2012 - 
TL;DR: In this paper, a search for third-generation leptoquarks and scalar bottom quarks in a sample of proton-proton collisions at 7 TeV collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 4.7 inverse femtobarns is presented.
Journal ArticleDOI

A Search for Single Photon Events in Neutrino Interactions

C.T. Kullenberg, +170 more
- 05 Jan 2012 - 
TL;DR: In this article, the authors present a search for neutrino induced events containing a single exclusive photon using data from the NOMAD experiment at the CERN SPS where the average energy of the neutrinos flux is ≃ 25 GeV.
Journal ArticleDOI

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
- 19 Jul 2017 - 
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
- 23 Nov 2018 - 
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.
