Search for Anomalous WW/WZ {r_arrow} e{nu}jj Production at D0; Busqueda de Produccion Anomala WW/WZ {r_arrow}e{nu}jj en D-Zero

A search for anomalous WW and WZ production in p{anti p} collisions at {radical}s = 1.8 TeV using the D0 detector at Fermilab is presented. With a data sample of p{anti p} {r_arrow} e{nu}jjX events corresponding to an integrated luminosity of 76.5 {+-} 4.1pb{sup {minus}1}. 399 candidate events were identified, from which 387.1 {+-} 39.8 events were estimated to be background. No deviations from the Standard Model were seen, which predicts 16.2 {+-} 2.7 events. The 95% CL limit on the cross section {sigma}(p{anti p} {r_arrow} W{sup +}W{sup {minus}}X) was calculated to be 93.8 pb. Limits on the CP-conserving anomalous WW{sub {gamma}} and WWZ coupling parameters were obtained from a binned likelihood fit to the transverse momentum spectrum of the W boson. Assuming that the WW{sub {gamma}} and WWZ coupling parameters are equal, the 95% CL limits on the CP-conserving couplings are {minus}0.56 < {Delta}{kappa} < 0.75 (with {lambda} = 0) and {minus}0.42 < {lambda} < 0.44 (with {Delta}{kappa} = 0), for a form factor scale {Lambda}{sub FF} = 1.5 TeV. Limits on other assumptions are also reported. These results were combined with the previous D0 WW, WZ {r_arrow} e{nu}jj published results (13.7 {+-} 0.7 pb{sup {minus}1}), and the limits …
