The single neutral top-higgs production at LHC and ILC in the Topcolor-Assisted Technicolor Model

In this paper, we study the single neutral top-higgs (h0) production processes at the CERN Large Hadron Collider (LHC) and the International Linear Collider (ILC). At the LHC, the production rates of processes pp →Z(W)h0 are too small to detect ht0. However, with the reasonable parameter values, the...

description In this paper, we study the single neutral top-higgs (h0) production processes at the CERN Large Hadron Collider (LHC) and the International Linear Collider (ILC). At the LHC, the production rates of processes pp →Z(W)h0 are too small to detect ht0. However, with the reasonable parameter values, the cross sections can reach the level of 102 fb for qq→qqh0process and 103 fb for top quark associated production process pp → th0 + X, respectively. At the ILC, we study the single top-higgs production processes e-y → veW-h0 and yy → W+W-h0 in e-y and yy collisions. It is found that the production cross sections can reach the level of a few t-b with reasonable parameter values. Furthermore, such processes with the flavor-changing decay mode h0 tO might provide typical signatures to detected the top-higgs. Therefore, it is hopeful to find the signal of top-higgs at the LHC and ILC experiments via theses processes and test the TC2 model directly.
