Modification of the rho meson detected by low-mass electron-positron pairs in central Pb-Au collisions at 158 A GeV/c

CERES Collaboration, D. Adamova

We present a measurement of $e^{+}{e}^{-}$ pair production in central Pb-Au collisions at 158$A$ GeV/$c$. As reported earlier, a significant excess of the $e^{+}{e}^{-}$ pair yield over the ex…
