Abstract We have studied high statistics samples of dimuon events (∼35,000) produced from π± on platinum target in the mass interval 4.2≦M μμ≦8.5 GeV at 150, 200 and 280 GeV/c. The π structure function is obtained by a fit ofd 2σ/dx 1 dx 2 to π+ and π− data. At 200 GeV, the simultaneous use of π+ and π− data allows a separate determination of the valence and sea structure functions of the π. Furthermore, the 150 and 280 GeV data allow an accurate determination of the shape of the valence structure function and give an estimate of its evolution betweenQ 2 =25 and 50 GeV2.
