The smallest drops of the Quark–Gluon plasma

High multiplicity pppp and pApA bins display elliptic and triangular flows, similar to that observed in AAAA collisions. We discuss why hydrodynamic description of such “small drops of QGP” should work, and in fact the main–radial–flow should even be stronger than in the textbook AAAA cases. We end up briefly discussing re-summation of high gradients.
