Abstract

Deep inelastic charged-current reactions have been studied in e(+)p and e(-)p collisions at a center of mass energy of about 300 GeV in the kinematic region Q(2)>200 GeV2 and x>0.006 using the ZEUS detector at HERA, The integrated cross sections for Q(2)>200 GeV2 are found to be sigma(e+p--><(upsilon)over bar X>)=30.3(-4.2 -2.6)(+5.5 +1.6) pb and sigma(e-p-->upsilon X)=54.7(-9.8 -3.4)(+15.9 +2.8) pb. Differential cross sections have been measures as functions of the variables x, y and Q(2). From the measured differential cross sections d sigma/dQ(2), the W boson mass is determined to be M(W)=79(-7 -4)(+8 +4) GeV. 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 sigma(e+p--><(upsilon)over bar X>)(Q(2)>200 GeV2; eta(max)<2.5)=0.8(-0.7)(+1.8)+/-0.1 pb.
