Symmetric cumulant $s{c}_{2,4}\left\{4\right\}$ and asymmetric cumulant $a{c}_2\left\{3\right\}$ from transverse momentum conservation and flow

Abstract

Multiparticle cumulants method can be used to reveal long-range collectivity in small and large colliding systems. The four-particle symmetric cumulant $s{c}_{2,4}\left\{4\right\}$, three-particle asymmetric cumulant $a{c}_2\left\{3\right\}$, and the normalized cumulants $ns{c}_{2,4}\left\{4\right\}$ and $na{c}_2\left\{3\right\}$ 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.
