Pseudorapidity dependence of long-range two-particle correlations in pPb collisions at s NN =5.02 TeV

Vardan Khachatryan, +2260 more
- 31 Jul 2017 - 
TL;DR: In this article, the pseudorapidity separation (Delta eta) of the particle pair at small relative azimuthal angle (abs(Delta phi) < pi/3) is decomposed into a jet component that dominates the short-range correlations and a component that persists at large Delta eta and may originate from collective behavior of the produced system.
Journal ArticleDOI

Studies of B-s2*(5840)(0) and B-s1(5830)(0) mesons including the observation of the B-s2*(5840)(0) -> (BKS0)-K-0 decay in proton- proton collisions at root s=8 TeV

Albert M. Sirunyan, +2299 more
- 15 Nov 2018 - 
TL;DR: In this article, the mass difference between the charged and neutral P-wave mesons is measured and the natural width of the meson state is determined. But the authors focus on the decay of mesons and do not consider the branching fraction of a meson.
Journal ArticleDOI

Search for narrow Hγ resonances in proton-proton collisions at √s =13 TeV

Albert M. Sirunyan, +2268 more
- 01 Mar 2019 - 
TL;DR: In this article, a search for heavy, narrow resonances decaying to a Higgs boson and a photon was performed in proton-proton collision data at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb-1.
Journal ArticleDOI

Forward energy flow, central charged-particle multiplicities, and pseudorapidity gaps in W and Z boson events from pp collisions at √s = 7 TeV

S. Chatrchyan, +4070 more
- 01 Jan 2012 - 
TL;DR: In this article, a study of forward energy flow and central charged-particle multiplicity in events with W and Z bosons decaying into leptons is presented using a sample of 7 TeV pp collisions, corresponding to an integrated luminosity of 36 inverse picobarns.
Journal ArticleDOI

Measurement of the Higgs boson width and evidence of its off-shell contributions to ZZ production

Armen Tumasyan, +2281 more
- 14 Feb 2022 - 
TL;DR: In this paper , the authors measured the width of the Higgs boson as 3.2 $-1.7}+2.4 MeV, in agreement with the standard model expectation of 4.1 MeV.
