Forbidden Dark Matter Combusted Around Supermassive Black Hole
Yu Cheng, Shao-Feng Ge, Xiao-Gang He +1
The forbidden dark matter cannot annihilate into a pair of heavier partners, either SM particles or its partners in the dark sector, at the late stage of cosmological evolution by…
Electroweak precision tests for triplet scalars
Yu Cheng, Xiao-Gang He, Fei Huang +2
Electroweak precision observables are fundamentally important for testing the standard model (SM) or its extensions. The influences to observables from new physics within the elect…
Dark photon kinetic mixing effects for the CDF W-mass measurement
Yu Cheng, Xiao-Gang He, Fei Huang +2
A new gauge boson primarily interacting with a dark sector can have renormalizable kinetic mixing with the standard model (SM) gauge boson . This mixing be…
Type-II Seesaw Triplet Scalar Effects on Neutrino Trident Scattering
Yu Cheng, Xiao-Gang He, Zhong-Lv Huang +1
In Type-II seesaw model, an electroweak triplet scalar field with a non-zero vacuum expectation value (vev) is introduced to facilitate the generation of small neutrino m…
Widening the mass range for resolving the muon anomaly
Yu Cheng, Xiao-Gang He, Jin Sun
Exchanging a gauge boson is a favored mechanism to solve the muon anomaly. Among such models the from gauge group has been extensi…
CP violating dark photon kinetic mixing and type-III seesaw model
Yu Cheng, Xiao-Gang He, Michael J. Ramsey-Musolf +1
The hypothetical dark photon portal connecting the visible and dark sectors of the Universe has received considerable attention in recent years, with a focus on CP-conserving kinet…
Flavor Specific Gauge Model for Muon and Anomalies
Jian-Yong Cen, Yu Cheng, Xiao-Gang He +1
The muon and induced anomalies as hints of new physics beyond the standard model (SM) have attracted much attention. These two anomalies indicate tha…
Structure Of Flavor Changing Goldstone Boson Interactions
Jin Sun, Yu Cheng, Xiao-Gang He
General flavor changing interactions for a Goldstone boson (GB) to fermions due to a spontaneous global symmetry breaking are discussed. This GB may be the Axion, solving…
Flavor-changing Majoron interactions with leptons
Yu Cheng, Cheng-Wei Chiang, Xiao-Gang He +1
When the Standard Model Higgs sector is extended with a complex singlet that breaks global lepton number symmetry spontaneously, a massless Goldstone boson called the Majoron J ari…
