Özet:

 

The time-dependent suppression probability P(t) of upsilon  particles has been estimated due to the screening when embedded in  the medium of quark gluon plasma where the screened  potential is represented by an optical potential of type  V(r,λ)=−[V0+iW01+exp((r−R)λ)]V(r,λ)=−[V0+iW01+exp((r−R)λ)]V(r,\lambda) = - [\frac{V_{0}+iW_{0}}{1+exp((r-R)\lambda)}].  A similar type of variation of suppression probability has been  obtained by others. It has been observed that t12t12t_{\frac{1}{2}}  for melting of ΥΥ\Upsilon is ∼∼\sim 1.5 fm/c. The variation of the  screening radii of heavy mesons (J/ψ,Υ)(J/ψ,Υ)(J/\psi, \Upsilon) for 1S and 2S  states with respect to plasma radius have also been investigated  with the same complex screening potential. We have found that the  more highly excited state (2S) is less tightly bound and has a  larger effective radius than the ground state.
