Chiral fermions, Gravity and GUTs
Lay Nam Chang, Chopin Soo
We discuss a global anomaly associated with the coupling of chiral Weyl fermions to gravity. The Standard Model based upon which has 15 fermions…
The Standard Model with gravity couplings
Lay Nam Chang, Chopin Soo
In this paper, we examine the coupling of matter fields to gravity within the framework of the Standard Model of particle physics. The coupling is described in terms of Weyl fermio…
The Gerasimov-Drell-Hearn Sum Rule and Current Algebras
Lay Nam Chang, Yigao Liang, Ron L. Workman
The status of the Gerasimov-Drell-Hearn sum rules for polarized inclusive photo-production on nucleons is reviewed. It is shown that results from currently available data compare f…
Phenomenological Consequences of Singlet Neutrinos
Lay Nam Chang, Daniel Ng, John N. Ng
In this paper, we study the phenomenology of right-handed neutrino isosinglets. We consider the general situation where the neutrino masses are not necessarily given by ,…
