Search for New Physics in High p_T Like-Sign Dilepton Events at CDF II

摘要

We present a search for new physics in events with two high p_T leptons of the same electric charge, using data with an integrated luminosity of 6.1 fb~(-1). The observed data are consistent with standard model predictions. We set 95% C.L. lower limits on the mass of doubly charged scalars decaying to like-sign dileptons, m_H~(±±) > 190-245 GeV/c~2, assuming 100% BR to ee, μμ or eμ.
