Inclusive Search for New Physics with Like-Sign Dilepton Events in pp [over¯] Collisions at sqrt [s]= 1.96 TeV (original) (raw)

We describe a search for anomalous production of events with two leptons (e or) of the same electric charge in pp collisions at a center-of-mass energy of 1.96 TeV. Many extensions to the standard model predict the production of two leptons of the same electric charge. This search has a significant increase in sensitivity compared to earlier searches. Using a data sample corresponding to 1 fbÿ1 of integrated luminosity recorded by the CDF II detector, we observe no significant excess in an inclusive selection (expect 33: 2 4: 7 events, observe ...
