A transport model study of multiparticle cumulants in p + p collisions at 13 TeV

Flow-like signals including the ridge structure observed in small collision systems that are similar to those large have led questions about onset of collectivity nuclear collisions. In this study, we use string melting version a multi-phase transport model with or without sub-nucleon geometry for proton study multiparticle cumulants p+p collisions at 13 TeV. Both versions can produce negative c2{4} values high multiplicities. addition, dependences and c2{2} on parton cross section σ found be strong non-monotonous, where only an intermediate range leads c2{4}. Furthermore, better describes multiplicity dependence c2{4}, demonstrating importance studies systems.
