Detecting t-quark pairs at p-barp colliders using transverse dilepton masses and jets
Hadronic tt-bar production with semileptonic decays of either or both t and t-bar quarks gives distinctive transverse-momentum correlations of electrons (or muons) and neutrinos. Multiple semileptonic modes of the t..-->..b..-->..c..-->..s decay cascades are statistically quite probable, but explicit calculations show that they scarcely affect the e..nu.. correlations. Opposite-sign dileptons, coming mainly from primary semileptonic decays of t and t-bar together, have correlations that also reflect the t-quark mass, but less decisively than the e..nu.. correlations. Events with large missing p/sub T/ and no identified leptons are also expected, at a rate comparable to high-p/sub T/ charged leptons. Distinctive broad jet signatures are also expected for all these events, with specific correlations of the trigger lepton and jet momenta.
