M. Derrick et al., MEASUREMENT OF CHARGED AND NEUTRAL-CURRENT E(-)P DEEP-INELASTIC SCATTERING CROSS-SECTIONS AT HIGH Q(2), Physical review letters, 75(6), 1995, pp. 1006-1011
Deep inelastic e-p scattering has been studied in both the charged cur
rent (CC) and neutral current (NC) reactions at momentum transfers squ
ared Q(2) above 400 GeV2 using the ZEUS detector at the HERA ep collid
er. The CC and NC total cross sections, the NC to CC cross section rat
io, and the differential cross sections d sigma/dQ(2) are presented. F
rom the Q(2) dependence of the CC cross section, the mass term in the
CC propagator is determined to be M(W) = 76 +/- 16 +/- 13 GeV.
