中文摘要：

Motivated by recent search results for the standard model (SM) Higgs boson at the Large Hadron Collider (LHC), we revisit the Higgs phenomenology in the littlest Higgs model with T-parity (LHT ). We present the signal strength modifier μ, respectively, for the main search channels qq′→jjh→ jjγγ, qq′→Vh→Vγγ, qq′→Vh→Vbb, gg→h→γγ, and gg→h→VV in the LH T model. It is found that an enhancement factor of 1.09-1.56 in the qq′→jjh→jjγγ channel can be obtained for this model in Case B with parameter f in the range 500-1000 GeV. However, the rates for bb, ττ are significantly suppressed relative to the SM predictions, which are still consistent with the current sensitivity. It is hoped that this will be further tested with larger integrated luminosity at the LHC.

Motivated by recent search results for the standard model （SM） Higgs boson at the Large Hadron Collider （LHC）, we revisit the Higgs phenomenology in the littlest Higgs model with T-parity （LHT）. We present the signal strength modifier ix, respectively, for the main search channels qq＇→ jjh → jjγγ, qq＇→Vh →Vγγ, qq＇→Vh→ Vbb, gg→ h→ γγ, and gg→h→ VV in the LHT model. It is found that an enhancement factor of 1.09-1.56 in the qq＇→jjh→jjγγ channel can be obtained for this model in Case B with parameter f in the range 500 1000 GeV. However, the rates for bb, ττ are significantly suppressed relative to the SM predictions, which are still consistent with the current sensitivity. It is hoped that this will be further tested with larger integrated luminosity at the LHC.
