Multi high charged scalars in the LHC searches and Majorana neutrino mass generations
Chian-Shu Chen, Chao-Qiang Geng, Da Huang +1
One natural way to understand the excess of the measured rate over the standard model (SM) expectation at the Large Hadron Collider (LHC) is to have charged scalar bosons,…
Note on 125 GeV Spin-2 particle
Chao-Qiang Geng, Da Huang, Yong Tang +1
A new boson around 125 GeV without specific spin has been observed by both ATLAS and CMS at the LHC. Since its decay into a diphoton excludes the spin-1 case by the Landau-Yang the…
Study of pesudoscalar transition form factors within light front quark model
Chao-Qiang Geng, Chong-Chung Lih
We study the transition form factors of the pesudoscalar mesons ( and ) as functions of the momentum transfer within the light-front quark model. We compare…
Direct CP Violation in Charm Decays due to Left-Right Mixing
Chuan-Hung Chen, Chao-Qiang Geng, Wei Wang
Motivated by the deviation from no CP violation hypothesis for the CP asymmetry (CPA) difference between and , reported recently by LHCb and…
Magnetic dipole moment and keV neutrino dark matter
Chao-Qiang Geng, Ryo Takahashi
We study magnetic dipole moments of right-handed neutrinos in a keV neutrino dark matter model. This model is a simple extension of the standard model with only right-handed neutri…
CP violation in from diquarks
Chuan-Hung Chen, Chao-Qiang Geng, Wei Wang
The explanation of the large CP asymmetries in decays observed by the LHCb collaboration is likely to call for new physics beyond the CKM paradigm. We exp…
