Effect of quarks on the formation and evolution of Z(3) walls and strings in relativistic heavy-ion collisions |

Content: |
We investigate the effects of explicit breaking of
Z(3) symmetry due to presence of dynamical quarks on
the formation and evolution of Z(3) walls and associated
QGP strings within Polyakov loop model. We carry out
numerical simulations of the first order quark-hadron phase
transition via bubble nucleation (which may be appropriate,
for example, at finite baryon chemical potential). Using
appropriate shifting of the order parameter in the Polyakov
loop effective potential, we calculate the bubble profiles
using bounce technique, for the true vacuum as well as for
the metastable Z(3) vacua, and estimate the associated
nucleation probabilities. These different bubbles are
then nucleated and evolved and resulting formation and
dynamics of Z(3) walls and associated strings is studied. |
