Massive torsion modes, chiral gravity, and the Adler-Bell-Jackiw anomaly

Lay Nam Chang, Chopin Soo

Regularization of quantum field theories introduces a mass scale which breaks axial rotational and scaling invariances. We demonstrate from first principles that axial torsion and…

Massive torsion modes from Adler-Bell-Jackiw and scaling anomalies

Lay Nam Chang, Chopin Soo

Regularization of quantum field theories introduces a mass scale which breaks axial rotational and scaling invariances. We demonstrate from first principles that axial torsion and…

Adler-Bell-Jackiw anomaly, the Nieh-Yan form, and vacuum polarization

Chopin Soo

We show from first principles, using explicitly invariant Pauli-Villars regularization of chiral fermions, that the Nieh-Yan form does contribute to the Adler-Bell-Jackiw (ABJ) ano…

The Weyl Theory of Fundamental Interactions: Is CPT violated?

Chopin Soo, Lay Nam Chang

We compare the conventional description of the interaction of matter with the four known forces in the standard model with an alternative Weyl description in which the chiral coupl…

Invariant Regularization of Anomaly-Free Chiral Theories

Lay Nam Chang, Chopin Soo

We present a generalization of the Frolov-Slavnov invariant regularization scheme for chiral fermion theories in curved spacetimes. local gauge symmetries of the theory, including…

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…
