Abstract.

The study of meson formation in quark-gluon plasma using a temperature-dependent Bethe-Salpeter formalism presented earlier, is now extended to a logarithmic and a combination of a Coulomb plus a square-root kernel. We are able to get good fits to the meson masses with both kinds of kernels and our present results are qualitatively similar to those obtained for the Coulomb plus a linear kernel.
