Study of charged-current ep interactions at Q(2)>200 GeV2 with the ZEUS detector at HERA

Deep inelastic charged-current reactions have been studied in e+p and e-p collisions at a center of mass energy of about 300GeV in the kinematic region Q2>200GeV2 and x>0.006 using the ZEUS detector at HERA. The integrated cross sections for Q2>200GeV2 are found to be {Mathemati...

Description
Résumé:Deep inelastic charged-current reactions have been studied in e+p and e-p collisions at a center of mass energy of about 300GeV in the kinematic region Q2>200GeV2 and x>0.006 using the ZEUS detector at HERA. The integrated cross sections for Q2>200GeV2 are found to be {Mathematical expression} and {Mathematical expression}. Differential cross sections have been measured as functions of the variables x, y and Q2. From the measured differential cross sections dσ/dQ2, the W boson mass is determined to be {Mathematical expression}. Measured jet rates and transverse energy profiles agree with model predictions. A search for charged-current interactions with a large rapidity gap yielded one candidate event, corresponding to a cross section of {Mathematical expression} © 1996 Springer-Verlag.
