Experimental determination of the pion and nucleon structure functions by measuring high-mass muon pairs produced by pions of 200 and 280 GeV/c on a platinum target

We measured the production of massive muon pairs on a platinum•target by pions of 200 and 280 GeV/c. The following number of dimuon events have been collected for M > 4 GeV/c 2 • (a) n- of 200 GeV/c: "'5900 events; (b) 71+ of 200 GeV/c: "&...

Sumario:We measured the production of massive muon pairs on a platinum•target by pions of 200 and 280 GeV/c. The following number of dimuon events have been collected for M > 4 GeV/c 2 • (a) n- of 200 GeV/c: "'5900 events; (b) 71+ of 200 GeV/c: "'2200 events; (c) 71- or 280 GeV/c: "' 5700 events. These data were analysed in terms of the Drell-Yan model in order to obtain the pion and nucleon structure functions, which are parametrised with expres- sions of the form xa(l - x)B. Our results are compared to the structure functions obtairied in other experiments.
