Search for a standard model-like Higgs boson in the mass range between 70 and 110 GeV in the diphoton final state in proton-proton collisions at √s=8 and 13 TeV

Albert M. Sirunyan, +2333 more
- 10 Jun 2019 - 
TL;DR: The results of a search for a standard model-like Higgs boson decaying into two photons are presented in this paper, where the expected and observed 95% confidence level upper limits on the product of the cross section and branching fraction into two photon are presented.
Journal ArticleDOI

Measurement of the inclusive production cross sections for forward jets and for dijet events with one forward and one central jet in pp collisions at √s = 7 TeV

S. Chatrchyan, +2305 more
TL;DR: In this article, the double differential cross sections with respect to pt and eta are compared to predictions from three approaches in perturbative quantum chromodynamics: (i) next-to-leading-order calculations obtained with and without matching to parton-shower Monte Carlo simulations, (ii) PYTHIA and HERWIG partonshower event generators with different tunes of parameters, and (iii) CASCADE and HEJ models, including different non-collinear corrections to standard single-parton radiation.
Journal ArticleDOI

Search for New Physics with a Monojet and Missing Transverse Energy in pp Collisions at √s=7 TeV

S. Chatrchyan, +2244 more
- 10 Nov 2011 - 
TL;DR: A study of events with missing transverse energy and an energetic jet is performed using pp collision data at a center-of-mass energy of 7 TeV, and significant extension of the current limits on parameters of new physics benchmark models is achieved.
Journal ArticleDOI

Search for singly and pair-produced leptoquarks coupling to third-generation fermions in proton-proton collisions at s=13 TeV

Albert M. Sirunyan, +2356 more
- 10 Aug 2021 - 
TL;DR: In this article, a search for leptoquarks produced singly and in pairs in proton-proton collisions is presented, where the lepton is considered to be a scalar particle of charge −1/3e coupling to a top quark plus a tau lepton ( t τ ) or a bottom quark including a neutrino ( b ν ), or a vector particle of a charge +2/3 e coupling to t ν or b τ.
Journal ArticleDOI

Measurement of the Isolated Prompt Photon Production Cross Section in $pp$ Collisions at $\sqrt{s} = 7$~TeV

Vardan Khachatryan, +2173 more
- 23 Feb 2011 - 
TL;DR: The differential cross section for the inclusive production of isolated prompt photons has been measured as a function of the photon transverse energy E(T)(γ) in pp collisions at √s=7 TeV using data recorded by the CMS detector at the LHC to be in agreement with next-to-leading-order perturbative QCD calculations.
