Technicolor Mechanisms for Single Top Production
Abstract
We investigate the contribution of technicolor mechanisms to the production of single top quarks at hadron colliders. We find that a promising candidate process is gluon-gluon fusion to produce a W-boson plus technipion, with subsequent decay of the technipion to a top quark plus a bottom quark. The top-plus-bottom mode is the dominant one when the technipion mass is larger than the top mass. We calculate the total cross section and the distribution for the technipion production at Tevatron and LHC energies for a range of technipion masses, starting at 200 GeV. The decay chain of technipion to top plus bottom quarks and then top to W plus bottom yields a final state with two W's and two bottom quarks. We study the backgrounds to our process and the kinematic cuts that maximize the signal to background. We report event rate estimates for the upgraded Tevatron and the LHC.
