Abstract: We study the process \gamma\gamma -> h -> b b_bar at ILC as a probe of different little Higgs models, including the simplest little Higgs model (SLH), the littlest Higgs model (LH), and two types of littlest Higgs models with T-parity (LHT-I, LHT-II). Com

Abstract: The left-right twin Higgs model predicts a light stable scalar \hat{S}, which is a candidate for WIMP dark matter. We study its scattering on nucleon and find that the cross section is below the CDMS II upper bound but can reach the SuperCDMS sensitivity.

Abstract: Little Higgs theory naturally predicts a light Higgs boson whose most important discovery channel at the LHC is the di-photon signal pp→h→γγpp→h→γγpp\to h\to \gamma\gamma. In this work we perform a comparative study for this signal in some typical little

Abstract: In order to explain the Tevatron anomaly of the top quark forward-backward asymmetry AtFBAFBtA_{FB}^t in the left-right twin Higgs model, we choose to give up the lightest neutral particle of h^h^\hat{h} field as a stable dark matter candidate. Then a new

Abstract: We confront the little Higgs theory with the LHC Higgs search data (up to 17 fb-1 of the combined 7 and 8 TeV run). Considering some typical models, namely, the littlest Higgs model, the littlest Higgs model with T parity (LHT-A and LHT-B), and the simple

Abstract: We examine the status of dark matter (heavy photon) in the littlest Higgs model with T parity (LHT) in light of the new results from the LHC Higgs search, the Planck dark matter relic density, and the XENON100 limit on the dark matter scattering off the n

Abstract: We discuss a scenario of the type-II two-Higgs-doublet model (2HDM) in which the bb?γγ rate of the Higgs pair production is enhanced due to the two nearly degenerate 125 GeV Higgs bosons (h, H). Considering various theoretical and experimental constraints

Abstract: In this paper, we interpret the 750 GeV diphoton excess in the Zee–Babu extension of the two-Higgs-doublet model by introducing a top partner ( T )/bottom partner ( B ). In the alignment limit, the 750 GeV resonance is identified as the heavy CP-even Higg

Abstract: In this paper we simultaneously explain the excesses of the 750 GeV diphoton, muon g-2 and h→μτ in an extension of the two-Higgs-doublet model (2HDM) with additional vector-like fermions and a CP-odd scalar singlet ( P ) which is identified as the 750 GeV

Abstract: We study the excesses of R(D(?))R(D(?))R(D^{(*)}) and muon g?2g?2g-2 in the framework of a two-Higgs-doublet model with top quark flavor-changing neutral-current (FCNC) couplings. Considering the relevant theoretical and experimental constraints, we find
