Cross-Section Measurements for Charm Production by 209-GeV Muons
Abstract
Interactions of 209-GeV muons in the multimuon spectrometer at Fermilab have yielded 20 072 dimuon final states, with (81+/-10)% attributed to production of charmed states decaying to muons. The cross section for diffractive charm muoproduction is 6.9+1.9-1.4 nb. Extrapolated to Q2=0, the effective cross section for 178- (100-) GeV photons is 750+180-130 (560+200-120) nb.
