| 摘 要： | We perform a comparative study for the LHC di-photon Higgs signal in three different littlest Higgs models with T-parity (named LHT-Ⅰ, LHT-Ⅱ and LHT-Ⅲ). We find that compared with the Standard Model prediction, the di-photon rate is always suppressed and the suppression extent can be different for different models. The LHC will soon give a solid judgement whether the di-photon rate is larger than the SM prediction, which can be utilized as a sensitive probe for the three models.
