We study the muon g-2 and neutralino dark matter as explained by the MSSM where the squarks and 3rd generation sleptons are decoupled. Particularly, we focus on constraints from current and future dark matter experiments such as PandaX-II and LUX-2016 as well as current bounds from collider searches. Using the constraints on the MSSM from the muon g-2 and DM searches, we study constraints from...

The determination of the electroweak properties of the stop will be an essential task for the LHC. We investigate the observability of single stop production through Mono-top/bottom channel in natural supersymmetry at the LHC.

We utilize the LHC Run-2 Higgs data to constrain the CP-violating top-Higgs coupling. Within the allowed parameter space, we study the impact of the CP-violating top-Higgs coupling in the Higgs production processes $pp \to t\bar{t}h, thj, hh$ at 14 TeV LHC, and $e^+e^- \to Zh, h\gamma$ at 240 GeV CEPC.

Recent reanlysis of ALEPH data seems to indicate dimuon excess around 30 GeV dimuon in Z -> b bar{b} mu^+ mu^- with a branching fraction around 1.1 X 10^{-5}. We discuss a few simplified models for the dimuon excess. In the first class of models, we assume a new resonance couples to both b bar{b} and mu^+ mu^-. Within the allowed parameter space for the ALEPH data, this type of models is...

Collaboration and long-standing inconsistency between theory and experiment
in muon anomalous magnetic moment are simultaneously explained by an extra
leptonic force mediated by a gauge field with a mass of the
MeV scale. With different assumptions for redshift distriution of
cosmic neutrino sources,... -

In previous work, it was found that if L_{\mu}-L_{\tau} massive Z' has a MeV-scale mass, muon g-2 problem and IceCube gap can be simultaneously explained. Then, I have studied the detectability of Z' at the future Belle II experiment. I'll propose a detectability of Z' through a one photon + missing process.

We argue that an exact gauge invariance may disable some generic features of the Standard Model which could otherwise manifest themselves at high energies. One of them might be related to the spontaneous Lorentz invariance violation (SLIV) which could provide an alternative dynamical approach to QED and Yang-Mills theories with photon and non-Abelian gauge fields appearing as massless...

model based on a dimension 7 gauge-invariant operator that violates the
lepton number by two units. The UV completion in this model includes a
scalar leptoquark doublet with hypercharge 1/6 and an additional vector-like
lepton doublet. It is shown that the neutrino mass matrix is proportional to
the masses of the heavy...
