摘      要：Within the context of the topcolor-assisted technicolor(TC2)model we investigate the associated production of the neutral top-higgs hto with a pair of top quarks,***→t_(t)hto at the Large Hadron Collider(LHC),which proceeds through the partonic processes q(q)→t_(t)hto and gg→t_(t)*** calculate the production rate and show the distributions of the transverse momenta of *** is found that the cross section of pp→t_(t)hot can reach a few hundred fb in the most part of the allowed parameter space and even a few tens of pb for the light *** to the large cross section of t_(t)hto production and the top-charm decay mode of h0t for mhto2mt,the process pp→t_(t)hto can play an important role in the probe of neutral top-higgs and the test of the TC2 model.
