J/ ψ and ψ ′ production cross-sections are measured in pp and pd collisions at 450 GeV/ c at the CERN-SPS. The Drell-Yan cross section for muon pairs in the mass range [4.3–8.0] GeV/ c 2 is also determined in the same experiment.

The measured cross section for J/PSI production for P P and P DEUTERIUM interactions times their branching ratio to MU+ MU- pairs.. The fraction of the systematic error (DSYS) which must be taken into account in comparison of the two targets is 0.06 (0.13) for the P (DEUT) target.

Table 2

The measured cross section for PSI(3685) production in P P and P DEUTERIUM interactions times their branching ratio to MU+ MU- pairs.. The fraction of the systematic error (DSYS) which must be taken into account in comparison of the two targets is 0.003 (0.006) for the P (DEUT) target.

Table 3

The measured cross section for Drell Yan production in P P and P DEUTERIUM interactions.. The fraction of the systematic error (DSYS) which must be taken into account in comparison of the two targets is 0.5 (1.2) for the P (DEUT) target.

Prompt dimuon production has been measured. Events with mass up to 25 GeV/c2 are observed, as well as the J and ϒ resonances. Cross sections are given for J and ϒ production. For the continuum, the scaling function F(τ) is measured at very small values of τ=ms covering the range 0.05<τ<0.20.
