Search for new physics in high $p_T$ like-sign dilepton events at CDF~II

Abstract

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, $m_{H^{\pm \pm }}>190-245$ GeV/$c^2$, depending on the decay mode and coupling.
