Event activity dependence of (nS) production in=5.02 TeV pPb and=2.76 TeV pp collisions
(Springer Science+Business Media, 2014-04)The production of (1S), (2S), and (3S) is investigated in pPb and pp collisions at centre-of-mass energies per nucleon pair of 5.02 TeV and 2.76 TeV, respectively. The datasets correspond to integrated luminosities of about ... -
Investigation into the event-activity dependence of ϒ(nS) relative production in proton-proton collisions at s√ = 7 TeV
(Springer Nature, 2020-11-02)The ratios of the production cross sections between the excited gamma(2S) and gamma(3S) mesons and the gamma(1S) ground state, detected via their decay into two muons, are studied as a function of the number of charged ... -
Observation of gamma(1S) pair production in proton-proton collisions at root s=8 TeV
(Springer International Publishing , 2017)Pair production of gamma(1S) mesons is observed at the LHC in proton-proton collisions at root s = 8 TeV by the CMS experiment in a data sample corresponding to an integrated luminosity of 20.7 fb(-1). Both gamma(1S) ...
