Measurement of charged and neutral current $e-p$ deep inelastic scattering cross sections at high \(Q^{2}\)

Deep inelastic e-p scattering has been studied in both the charged current (CC) and neutral current (NC) reactions at momentum transfers squared Q 2 above 400 GeV 2 using the ZEUS detector at the HERA ep collider. The CC and NC total cross sections, the NC to CC cross section ratio, and the differential cross sections dσ/dQ 2 are presented. From 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.
