Matter induced -δ mixing : a source of dileptons
O. Teodorescu, A. K. Dutt-Mazumder, C. Gale
Abstract
We study the possibility of -δ mixing via N-N excitations in dense nuclear matter. This mixing induces a peak in the dilepton spectra at an invariant mass equal to that of the δ. We calculate the cross section for dilepton production through the mixing process and we compare its size with that of π-π annihilation. In-medium masses and mixing angles are also calculated.
