Effects of the littlest Higgs model with T-parity on Higgs boson production at high energy e+e− colliders Chong-Xing Yue and Nan Zhang 6 Department of Physics, Liaoning Normal University, Dalian 116029, China∗ 0 0 2 February 2, 2008 v o N 7 1 Abstract 2 The Higgs boson production processes e+e− → ZH , e+e− → ν¯ ν H , and v e e 7 + − ¯ 4 e e → ttH are very important for studying Higgs boson properties and further 2 9 testing new physics beyond the standard model(SM ) in the high energy linear e+e− 0 6 collider(ILC ). We estimate the contributions of the littlest Higgs model with T- 0 / parity(LHT model) to these processes and find that the LHT model can generate h p - significantly corrections to the production cross sections of these processes. We ex- p e pect the possible signals of the LHT model can be detected via these processes in h : the future ILC experiments. v i X r a ∗E-mail:cxyue@ 1 The discovery and study of Higgs boson is one of the most important goals of present and future high energy collider experiments[1]. The physics of the Higgs boson will be explored by high energy experiments at the upgraded Tevatron collider at Fermlab and in the near future at the large hadron collider at CERN (LHC). The LHC will make the first exploration of the TeV energy range, and will be able to discover Higgs boson in the full mass range, provided it exists[2]. After discovery of the Higgs boson at the LHC , one of the most pressing tas
