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.
