Title: Search for new physics in high pT like-sign dilepton events at CDF II

We present a search for new physics in events with two high pT 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, mH±± > 190 - 245 GeV/c2, depending on the decay mode and coupling.
