Deep inelastic {ital e}{sup {minus}}{ital p} scattering has been studied in both the charged current (CC) and neutral current (NC) reactions at momentum transfers squared {ital Q}{sup 2} above 400GeV{sup 2} using the ZEUS detector at the HERA {ital ep} collider. The CC and NC total cross sections, the NC to CC cross section ratio, and the differential cross sections {ital d}{sigma}/{ital dQ}{sup 2} are presented. From the {ital Q}{sup 2} dependence of the CC cross section, the mass term in the CC propagator is determined to be {ital M}{sub {ital W}}=76{plus_minus}16{plus_minus}13 GeV.
