Light Dark Matter from the U(1)XU(1)XU(1)_X Sector in the NMSSM with Gauge Mediation

Kang,Z; Li,T; Liu,T; Tong,C; Yang,JM
Subjects:

Cosmic ray anomalies observed by PAMELA and Fermi-LAT experiments may be interpreted by heavy (TeV-scale) dark matter annihilation enhanced by Sommerfeld effects mediated by a very light (sub-GeV) U(1)_X gauge boson, while the recent direct searches from

Semi-direct Gauge-Yukawa Mediation

Kang,Z; Li,T; Liu,T; Yang,JM
Subjects:

We propose semi-direct Gauge-Yukawa mediation of supersymmetry (SUSY) breaking. The messenger fields mediating SUSY breaking to the visible sector do not directly couple with the goldstino field, and instead they have gauge and Yukawa interactions with so

Higgs self-coupling in the MSSM and NMSSM after the LHC Run 1

Wu,L; Yang,JM; Yuan,C; Zhang,M
Subjects:

Measuring the Higgs self-coupling is one of the crucial physics goals at the LHC Run-2 and other future colliders. In this work, we attempt to figure out the size of SUSY effects on the trilinear self-coupling of the 125 GeV Higgs boson in the MSSM and NM

Supersymmetric QCD corrections to single top quark production at the Fermilab Tevatron

Li,C; Oakes,RJ; Yang,J; Zhou,H
Subjects:

We evaluate the supersymmetric QCD corrections to single top quark production via qq?′→tb?qq?′→tb?q \bar q'\to t \bar b at the Fermilab Tevatron in the minimal supersymmetric model. We find that within the allowed range of squark and gluino masses the sup

We examine the possibility of observing exotic top quark decays via R-violating SUSY interactions at the Fermilab Tevatron and CERN LHC. We present cross-sections for tt?tt?t\bar t production followed by the subsequent decay of either ttt or t?t?\bar t vi

Higgs boson decays and production via gluon fusion at LHC in littlest Higgs models with T parity

Wang, Lei; Yang, Jin Min
Subjects: Physics >> The Physics of Elementary Particles and Fields

We study the Higgs boson decays and production via gluon fusion at the LHC as a probe of two typical littlest Higgs models which introduce a top quark partner with different (even and odd) T parity to cancel the Higgs mass quadratic divergence contributed by the top quark. For each model, we consider two different choices for the down-type quark Yukawa couplings. We first examine the branching ratios of the Higgs boson decays and then study the production via gluon fusion followed by the decay into two photons or two weak gauge bosons. We find that the predictions can be quite different for different models or different choices of down-type quark Yukawa couplings, and all these predictions can sizably deviate from the standard model predictions. So the Higgs boson processes at the LHC can be a sensitive probe for these littlest Higgs models.
