Search for a heavy particle decaying to a top quark and a light quark in pp collisions at s=1.96 TeV. Academic Article uri icon

abstract

  • We present a search for a new heavy particle X produced in association with a top quark, pp[over ]t(Xt[over ]q) or pp[over ]t[over ](X[over ]tq[over ]), where q stands for up quarks and down quarks. Such a particle may explain the recent anomalous measurements of top-quark forward-backward asymmetry. If the light-flavor quark (q) is reconstructed as a jet (j), this gives a t[over ]+j or t+j resonance in tt[over ]+jet events, a previously unexplored experimental signature. In a sample of events with exactly one lepton, missing transverse momentum and at least five jets, corresponding to an integrated luminosity of 8.7 fb(-1) collected by the CDF II detector, we find the data to be consistent with the standard model. We set cross-section upper limits on the production (pp[over ]Xt or X[over ]t[over ]) at 95% confidence level from 0.61 pb to 0.02 pb for X masses ranging from 200 GeV/c(2) to 800 GeV/c(2), respectively.
