Investigation into the event-activity dependence of ϒ(nS) relative production in proton-proton collisions at s $$ \sqrt{s} $$ = 7 TeV

Abstract The ratios of the production cross sections between the excited ϒ(2S) and ϒ(3S) mesons and the ϒ(1S) ground state, detected via their decay into two muons, are studied as a function of the number of charged particles in the event. The data are from prot...
