Inclusive muon pair production by 225 GeV/c $\pi^+, \pi^-$ and proton beams incident upon carbon and tin tarjets was measured over a large range of kinematic variables ($2m_{\mu} < m_{mm}$ < $1 GeV/c^2$, 0 < $x_F$ < $p_{\perp}$ < 4 GeV/c and $\mid cose^* 1 < .3$)...

We present the analysis of ∼30,000 high mass dimuons (Mμμ>4.5 GeV/c2) produced in 400 GeV/c proton-platinum interactions. A determination of theK-factor is given for different values ofxF andMμμ, and its variations are compared to QCD predictions. The proton structure functions derived from these events are compared to the values obtained in deep inelastic lepton scattering.
