Analysis of the HELIOS-3 ${\mu }^{+}{\mu }^{-}$ Data within a Relativistic Transport Approach

W. Cassing, W. Ehehalt, I. Kralik

We present a nonperturbative dynamical study of ${\mu }^{+}{\mu }^{-}$ production in proton-nucleus and nucleus-nucleus collisions at SPS energies on the basis of the covariant transport approac…
