Top quark FCNC decays and productions at LHC in littlest Higgs model with T-parity

Han,X; Wang,L; Yang,JM
分类:

In the littlest Higgs model with T-parity (LHT) the newly introduced mirror quarks have flavor-changing couplings with the Standard Model (SM) quarks and may enhance the flavor-changing neutral-current (FCNC) top quark interactions which are extremely sup

Higgs-pair Production and Decay in Simplest Little Higgs Model

Han,X; Wang,L; Yang,JM
分类:

In the framework of the simplest little Higgs model (SLHM), we study the production of a pair of neutral CP-even Higgs bosons at the LHC. First, we examine the production rate and find that it can be significantly larger than the SM prediction. Then we in

Higgs boson production in photon-photon collision at ILC: a comparative study in different little Higgs models

Wang,L; Xu,F; Yang,JM
分类:

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

Dark matter and Higgs phenomenology predicted by left-right twin Higgs model in light of CDMS II results

Wang,L; Yang,JM
分类:

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.

Top quark forward-backward asymmetry, FCNC decays and like-sign pair production as a joint probe of new physics

Cao,J; Wang,L; Wu,L; Yang,JM
分类:

The anomaly of the top quark forward-backward asymmetry AtFBAFBtA^t_{FB} observed at the Tevatron can be explained by the t-channel exchange of a neutral gauge boson (Z') which has sizable flavor changing coupling for top and up quarks. This gauge boson c

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

Wang,L; Yang,JM
分类:

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

Testing new physics models by top charge asymmetry and polarization at the LHC

Cao,J; Hikasa,K; Wang,L; Wu,L; Yang,JM
分类:

As a top quark factory, the LHC can test the new physics models used to explain the top quark forward-backward asymmetry A^t_FB measured at the Tevatron. In this work we perform a comparative study for two such models: the W'-model and the color triplet d

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

Wang,L; Wu,L; Yang,JM
分类:

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,J
分类:

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

Higgs decay to goldstini and its observability at the LHC

Liu,T; Wang,L; Yang,JM
分类:

If supersymmetry is broken independently in multiple sectors with different scales, a number of goldstinos will be generated. One linear combination of these goldstinos is massless and eaten by the gravitino, while the orthogonal combinations acquire a tr
