The initial global rotation entails a nontrivial dependence of the longitudinal flow velocity on the transverse coordinates and also develops a transverse velocity component that depends upon longitudinal coordinate. Both of these velocities leads to a 2+1 dimensional expansion of the fireball. It is observed that with the finite vorticity and spin-polarization fireball cools faster in comparison with the case without vorticity. Furthermore, we also discuss the consequence of this on thermal dilepton production.en-USHigh Energy PhysicsPhenomenologye-Printe-Print123456789/615
