Recently,the Muon g-2 experiment at Fermilab measured the muon anomalous magnetic dipole moment(MDM),aμ=(gμ-2)/2,and reported that the new experimental average increases the difference between the experiment and the...

The BLMSSM is an extension of the minimal supersymmetric standard model(MSSM).Its local gauge group is SU(3)C×SU(2)L×U(1)Y×U(1)B×U(1)L.Supposing the lightest scalar neutrino is a dark matter candidate,we study the...

We show that the signature of two boosted W-jets plus substantial missing energy is very promising for probing heavy charged resonances(X^(±))through the process of pp→X^(+)X^(-)→W^(+)W^(-)X^(0) X^(0),where X^(0) d...

In this work,we study the implications of Higgs precision measurements at future Higgs factories for the MSSM parameter space,focusing on the dominant stop sector contributions.We perform a multivariable fit to both t...
We present a SUSY model with four Higgs doublets of the"private type,"in which all fermion types(up,down,and charged leptons)obtain their masses from a different Higgs doublet H_f(f=u_1,d,e) .The conditions for anomal...

Using the latest PandaX limits on the light dark matter(DM) with a light mediator, we check their implication on the parameter space of the general singlet extension of MSSM(without Z3 symmetry), which can have a suff...

In past years,several hints of lepton flavor universality(LFU)violation have emerged from the b→ct■,and b→sl+l-data.More recently,the Belle Collaboration has reported the first measurement of the D* longitudinal ...

The deviation of the measurement of RD (RD*) from the Standard Model (SM) expectation is 2.3σ (3.1σ). RD (RD*) is the ratio of the branching fraction of ^-B→Dτ^-υτ (^-B→D^*τ^-υτ ) to that of ^-B...

Electroweak WIMPs are under intense scrutiny from direct detection, indirect detection, and collider experiments. Nonetheless the pure(pseudo-Dirac) higgsino, one of the simplest such WIMPs, remains elusive. We pres...
