Direct muon production in proton-nuclear collisions at 70, 50 and 35 GeV

Direct muon yields (μ ±) in the transverse momentum range of 1.9–3.1 GeV/ c on Cu and Be nuclei at the proton energies 70, 50 and 35 GeV have been measured. The yield of direct μ/π is shown to considerably decrease when proton energy varies from 70 to 35 GeV. The charge ratio of direct muon μ +/μ −...

Description
Summary:Direct muon yields (μ ±) in the transverse momentum range of 1.9–3.1 GeV/ c on Cu and Be nuclei at the proton energies 70, 50 and 35 GeV have been measured. The yield of direct μ/π is shown to considerably decrease when proton energy varies from 70 to 35 GeV. The charge ratio of direct muon μ +/μ − as well as the dependence of the yield of direct muons on the atomic number of the target have been measured.
