Higgs precision study of the 750 GeV diphoton resonance and the 125 GeV standard model Higgs boson with Higgs-singlet mixing
Kingman Cheung, P. Ko, Jae Sik Lee +2
We interpret the potential observation of the 750 GeV di-photon resonance at the LHC in models, in which an isospin-singlet scalar boson mixes with the Standard Model (SM)…
Leptoquark induced rare decay amplitudes and
Kingman Cheung, Wai-Yee Keung, Po-Yan Tseng
Rare decay modes of the newly discovered standard-model-like Higgs boson may test the flavor changing couplings in the leptoquark sector through the process .…
Bounds on Higgs-Portal models from the LHC Higgs data
Kingman Cheung, P. Ko, Jae Sik Lee +1
In a number of Higgs-portal models, an isospin-singlet scalar boson generically appears at the electroweak scale and can mix with the Standard Model (SM) Higgs boson with a…
Interpretations of the ATLAS Diboson Anomaly
Kingman Cheung, Wai-Yee Keung, Po-Yan Tseng +1
Recently, the ATLAS Collaboration recorded an interesting anomaly in diboson production with excesses at the diboson invariant mass around 2 TeV in boosted jets of all the , $W…
Dark Matter with multi-annihilation channels and AMS-02 positron excess and antiproton
Yu-Heng Chen, Kingman Cheung, Po-Yan Tseng
AMS-02 provided the unprecedented statistics in the measurement of the positron fraction from cosmic rays. That may offer a unique opportunity to distinguish the positron spectrum…
Higgs data constraints on the minimal supersymmetric standard model
Kingman Cheung, Jae Sik Lee, Po-Yan Tseng
We perform global fits to the most recent data (after summer 2014) on Higgs boson signal strengths in the framework of the minimal supersymmetric standard model (MSSM). We further…
