Description
The azimuthal cumulants, $c_2\{2\}$ and $c_2\{4\}$, originating from the global conservation of transverse momentum [1] in the presence of hydro-like elliptic flow are calculated [2]. We observe a sign change of $c_2\{4\}$ for small number of produced particles, which is in a qualitative agreement with the recent ATLAS measurement of multi-particle azimuthal correlations with the subevent cumulant method [3]. Our results offer a new insight into the problem of the onset of collectivity in small systems.
