摘要: Abstract Muons of high transverse momentum p μ T have been observed in the large drift chambers surrounding UA1 detector at CERN 540 GeV pp collider. For an integrated luminosity 108 nb −1 , 14 isolated muons found with > 15 GeV/ c . They are correlated a imbalance total energy, and show kinematic behaviour consistent muonic decay Intermediate Vector Boson W ± weak interactions. The partial cross section is agreement previous measurements for electronic decays muon-electron universality. mass determined to be m = 81 +6 −7 2
