We use low mass dimuons (0.35 < M μμ ⩽ 2 GeV/ c 2 ) to analyse the production at high transverse momentum ( P T ⩾ 2 GeV/ c ) of the resonances ϱ, ω, π. We have studied the variation of the cross section with the type of incident particle (π, K, p) at 150, 200, 280 GeV/ c and the nuclear effects by comparison of platinum and hydrogen targets. There is no significant difference between the slopes of the transverse momentum distributions with those observed at lower P T (0 < P T < 2 GeV/ c ), meanwhile x F -distributions show a leading effect in the production of gf by kaons at these relatively high transverse momenta.
