Abstract
The e(+)p charged-current deep inelastic scattering cross sections, d sigma /dQ(2) for Q(2) between 200 and 60000 GeV2, and d sigma/dx and d sigma/dy f or Q(2) > 200 GeV2, have been measured with the ZEUS detector at HERA. A da ta sample of 47.7 pb(-1), collected at a center-of-mass energy of 300 GeV, has been used. The double-differential cross-section d sigma/dQ(2) falls by a factor of about 50000 as Q(2) increases from 280 to 30000 GeV2. The doub le differential cross section d(2)sigma/dxdQ(2) has also been measured. A c omparison between the data and Standard Model (SM) predictions shows that c ontributions from antiquarks ((u) over bar and (c) over bar) and quarks (d and s) are both required by the data. The predictions of the SM give a good description of the full body of the data presented here. A comparison of t he charged-current cross-section d sigma/dQ(2) with the recent ZEUS results for neutral-current scattering shows that the weak: and electromagnetic fo rces have similar strengths for Q(2) above M-W(2), M-Z(2). A fit to the dat a for d sigma/dQ(2) with the Fermi constant G(F) and M-W as free parameters yields G(F) = (1.171 +/- 0.034 (stat.)(-0.032)(+0.026) (syst.) (+0.016)(-0 .015)(PDF)) x 10(-5) GeV-2 and M-W = 80.8(-4.5)(+4.9) (stat.) (+5.0)(-4.3) (syst.) (+1.4)(-1.3) (PDF) GeV. Results for M-W, where the propagator effec t alone or the SM constraint between G(F) and M-W have been considered, are also presented.
