Albert M. Sirunyan, +30 more
- 11 Aug 2021 -

S. Chatrchyan, +2226 more
- 10 Jul 2017 - 
TL;DR: In this article, the mass difference between the top quark and antiquark ( Δ m t = m t − m t ‾ ) that are produced in pp collisions at a center-of-mass energy of 8 TeV, using events with a muon or an electron and at least four jets in the final state.
Journal ArticleDOI

Search for resonant pair production of Higgs bosons in the bbZZ channel in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2348 more
- 12 Aug 2020 - 
TL;DR: In this paper, a search for the production of a narrow-width resonance decaying into a pair of Higgs bosons decaying into the bbZZ channel is presented, based on data collected with the CMS detector during 2016, in proton-proton collisions at the LHC.
Journal ArticleDOI

Measurement of the energy density as a function of pseudorapidity in proton–proton collisions at √s=13TeV

Albert M. Sirunyan, +2255 more
- 07 May 2019 - 
TL;DR: In this paper, a measurement of the energy density in proton-proton collisions at a center-of-mass energy of sTeV is presented and compared with the predictions of several models, which suggest a different shape of the pseudorapidity dependence compared to that observed in the data.
