Evidence for electroweak production of four charged leptons and two jets in proton-proton collisions at s=13TeV

Albert M. Sirunyan, +2363 more
- 10 Jan 2021 - 
TL;DR: In this article, evidence for the electroweak production of two jets (jj) in association with two Z bosons and constraints on anomalous quartic gauge couplings are set.
Journal ArticleDOI

Search for nonresonant Higgs boson pair production in the b b ¯ b b ¯ final state at √s = 13 TeV

Albert M. Sirunyan, +2375 more
- 17 Apr 2019 - 
TL;DR: The results of a search for non-resonant production of Higgs boson pairs, with each Higgs particle decaying to a $ \mathrm{b}overline{b}} pair, are presented in this article.
Journal ArticleDOI

First measurement of large area jet transverse momentum spectra in heavy-ion collisions

Albert M. Sirunyan, +2369 more
- 01 May 2021 - 
TL;DR: In this article, the effects of jet suppression on PbPb and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV were studied with the CMS detector at the LHC.
Journal ArticleDOI

Measurement of the ratio of the production cross sections times branching fractions of B-c(+/-) -> J/psi pi(+/-) and B-+/- -> J/psi K-+/- and B(B-c(+/-) -> J/psi pi(+/-)pi(+/-)pi(-/+))/B(B-c(+/-) -> J/psi pi(+/-)) in pp collisions at root s=7 Tev

Vardan Khachatryan, +2205 more
- 13 Jan 2015 - 
TL;DR: In this article, a model-independent method was developed to measure the efficiency given the presence of resonant behavior in the three-pion system, and the ratio of the branching fractions B(B^±_c → J/ψπ^±ππ+πππ^∓)/B(B+c → ψπ+k+π+1.5 (T_B_c) was measured to be 2.55±0.80 (stat)± 0.03 (syst) ± 0.33 (+0
Journal ArticleDOI

Measurements of Higgs boson production cross sections and couplings in the diphoton decay channel at s√= 13 TeV

Albert M. Sirunyan, +2405 more
- 07 Jul 2021 - 
TL;DR: In this article, the authors measured the Higgs boson signal strength relative to the standard model (SM) prediction, including SM signal strength modifiers, production cross sections, and its couplings to other particles.
