Description
Summary:Multiparticle cumulants method can be used to reveal long-range collectivity in small and large colliding systems. The four-particle symmetric cumulant s c 2 , 4 { 4 } , three-particle asymmetric cumulant a c 2 { 3 } , and the normalized cumulants n s c 2 , 4 { 4 } and n a c 2 { 3 } from the transverse momentum conservation and flow are calculated. The interplay between the two effects is also investigated. Our results are in a good agreement with the recent ATLAS measurements of multiparticle azimuthal correlations with the subevent cumulant method, which provides insight into the origin of collective flow in small systems.
