The influence of Debye plasma on the ground state energies of exotic systems

The effect of plasma environment on the ground state energies of exotic systems ppμ, ddμ and ttμ has been analyzed within a generalized three-body formalism using multi-term correlated basis sets. The Debye screening model of the plasma has been adopted for such a study. The binding energies of p with pμ, d with dμ and t with tμ have been estimated for a range of values of the Debye screening parameters. The systems tend toward instability for increased screening. The effect of particle correlation has been investigated in detail and is found to play an important role for the stability in these systems.
