Quest for deconfined quark phase: A new avenue

Abstract
Stability of droplets of ud matter, viz udilets, is studied using non-relativistic and relativistic bag models. It is found that there is a strong possibility for forming hypercharged metastable udilets with charge fraction Z/A 1 in semicentral relativistic heavy ion collisions. It is then speculated that protons hadronised from these hypercharged udilets may be contributing towards the directed sideward flow observed recently in experiment. This exotic state with large charge to mass ratio presents an unique possibility for the spontaneous emission of positrons due to the `sparking' of the vacuum.
