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 |

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. |

The LHC di-photon Higgs signal predicted by little Higgs models

Wang,L; Yang,JMSubjects:

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 |

Top quark forward-backward asymmetry and charge asymmetry in left-right twin Higgs model

Wang,L; Wu,L; Yang,JMSubjects:

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 |

Little Higgs theory confronted with the LHC Higgs data

Han,X; Wang,L; Yang,JM; Zhu,JSubjects:

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 |

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 |

Higgs pair signal enhanced in the 2HDM with two degenerate 125 GeV Higgs bosons

Han,X; Wang,L; Yang,JMSubjects:

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 |

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 |

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 |

Probing a pseudoscalar at the LHC in light of R(D(?))R(D(?))R(D^{(*)}) and muon g-2 excesses

Wang,L; Yang,JM; Zhang,YSubjects:

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 |
