| Description |
We study the formation of Z(3) domains in a confinement- deconfinement
phase transition in relativistic heavy-ion collisions. The transition
is modelled in the framework of Polyakov loop which provides an order
parameter for the transition. Existence of different Z(3) domains can
lead to the formation of Z(3) interfaces and associated QGP
strings. We study the formation of these topological objects using a
first order transition (as appropriate for large chemical potential
situation) as well as using a quench which is likely to be the case
for relativistic heavy-ion collisions especially due to rapid initial
thermalization. Coarsening of Z(3) domain structure, Z(3) walls and
strings are studied. These can have important observational
implications, e.g. in terms of modified momentum distributions of
particles, and multiplicity fluctuations.
