Abstract

The like-sign dimuons copiously recorded in the NA 38 experiment both in p − U and O−U reactions at 200 GeV/nucleon are interpreted as resulting from decays of π and K mesons in comparable proportions. The + +/− − ratio is large (≃1.7) and ascribed to the K + being more copiously produced than the K . Both the average transverse momentum and the + +/− − ratio are comparable for p−U and O−U reactions, and both increase only slightly with the transverse energy E T .
