Surface Induced Phase Transition in Quark-Gluon Plasma Produced in Laboratory

We discuss an outside-inside scenario for a first order quark-hadron transition in the Quark-Gluon Plasma (QGP) expected to be produced in heavy ion collisions, wherein the entire QGP region itself becomes like a subcritical bubble, and starts shrinking. We argue that this shrinking QGP bubble will lead to concentration of baryon number in a narrow beam like region in center, which can be detected by HBT analysis, or as a raised plateau in the rapidity plot of baryon number.
