Study of Majorana Fermionic Dark Matter
Chun-Khiang Chua, Gwo-Guang Wong
We construct a generic model of Majorana fermionic dark matter (DM). Starting with two Weyl spinor multiplets coupled to the Standard Model (SM) Higgs, six…
Strong Decays of Charmed Baryons in Heavy Hadron Chiral Perturbation Theory: An Update
Hai-Yang Cheng, Chun-Khiang Chua
We first give a brief overview of the charmed baryon spectroscopy and discuss their possible structure and spin-parity assignments in the quark model. With the new Belle measuremen…
Bottom Baryon Decays to Pseudoscalar Meson and Pentaquark
Hai-Yang Cheng, Chun-Khiang Chua
Based on SU(3) flavor symmetry, we decompose the decay amplitudes of bottom baryon decays to a pseudoscalar meson and an octet (a decuplet) pentaquark in terms of three (two) invar…
Revisiting Scalar Glueballs
Hai-Yang Cheng, Chun-Khiang Chua, Keh-Fei Liu
It is commonly believed that the lowest-lying scalar glueball lies somewhere in the isosinglet scalar mesons and denoted generically by .…
