Meson Mixing and Dilepton Production in Heavy Ion Collisions
A. K. Dutt-Mazumder, C. Gale, O. Teodorescu
Abstract
We study the possibility of -a0 mixing via N-N excitations in dense nuclear matter. This mixing is found to induce a peak in the dilepton spectra at an invariant mass equal to that of the a0. We calculate the cross section for dilepton production through mixing and we compare its size with that of π-π annihilation. In-medium masses and mixing angles are also calculated. Some preliminary results of the mixing effect on the dilepton production rates at finite temperature are also presented.
