a Measurement of the Inclusive Differential Drell - Cross-Section with Dimuons at SQRT.S = 1.8 Tev.

The inclusive differential Drell-Yan cross section is measured from the analysis of |{p }ptogammatomu^+mu ^-X events at a center-of-mass energy of sqrt{s} = 1.8 TeV at the Fermilab Tevatron collider. The dimuon events are accepted in the central pseudorapidity region of -0.6<eta<0.6 of the CDF detector. The differential cross section dsigma/dMdY|_{Y=0} is measured for dimuon invariant masses between 11 GeV/c^2 and 40 GeV/c ^2 and is compared to next-to-leading order theoretical predictions. The sigma(Z^ circtomu^+mu^-) cross section is also measured.
