- Abstract
The critical values of screening parameters for Υ1S and Υ2S in Quark– Gluon Plasma (QGP) have been estimated, where the screened potential is represented by an optical potential of type V (r, λ) = -[ V0+iW0/1+exp((r-R)λ) ]. It has been observed that the critical screening length possesses smaller value indicating a larger suppression compared to the value obtained when the screened potential is represented by real potential. The variation of twoparticle energies of Υ1S and Υ2S with temperature has also been studied. It has been observed that below T = 0.8 Tc, the two-particle energy remains almost invariant before approaching to deconfinement phase at T = Tc. The results obtained are compared with other existing estimates.
