Observation of a New Excited Beauty Strange Baryon Decaying to Ξb- π+π-

Albert M. Sirunyan, +2345 more
- 25 Jun 2021 - 
TL;DR: In this article, an event sample of proton-proton collisions at 13 TeV was collected by the CMS experiment at the LHC in 2016-2018 and corresponding to an integrated luminosity of 140 fb$^{-1}.
Journal ArticleDOI

Investigation into the event-activity dependence of ϒ(nS) relative production in proton-proton collisions at √ s = 7 TeV

Albert M. Sirunyan, +2379 more
- 02 Nov 2020 - 
TL;DR: In this article, the production cross sections between excited ϒ(2S) and ϒ (3S) mesons and the ground state, detected via their decay into two muons, are studied as a function of the number of charged particles in the event.
Journal ArticleDOI

Inclusive production of ρ0(770), f0(980) and f2(1270) mesons in νμ charged current interactions

P. Astier, +165 more
- 07 May 2001 - 
TL;DR: In this article, the meson resonances of neutrino-nucleus charged current interactions were studied with the NOMAD detector exposed to the wide band neutrinos beam generated by 450 GeV protons at the CERN SPS.
Journal ArticleDOI
