Abstract
We report on measurements of low-mass electron pairs in 450 GeV p-Be, p-Au, and 200 GeV/nucleon S-Au collisions at central rapidities. For the proton induced interactions, the low-mass spectra are, within the systematic errors, satisfactorily explained by electron pairs from hadron decays, whereas in the S-Au system an enhancement over the hadronic contributions by a factor of 5.0±0.7(stat)±2.0(syst) in the invariant mass range 0.2
Presentamos mediciones de pares de electrones de baja masa en colisiones p-Be y p-Au a 450 GeV y S-Au a 200 GeV/nucleón a rapideces centrales. Para las interacciones inducidas por protones, los espectros de baja masa se explican satisfactoriamente, dentro de los errores sistemáticos, mediante pares de electrones procedentes de desintegraciones hadrónicas, mientras que en el sistema S-Au un realce respecto a las contribuciones hadrónicas por un factor de 5.0±0.7(estat)±2.0(sist) en el rango de masa invariante 0.2
