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, i.e.pp→t(t)hto at the Large Hadron Collider(LHC), which proceeds through the partonic processes q(q)→t(t)hto and gg→t(t)hto.We calculate the production rate and show the distributions of the transverse momenta of hto.It 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 top-higgs.Due to the large cross section of t(t)hto production and the top-charm decay mode of h0t for mhto＜2mt, 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.
