An Empty Chiral Rotation for the Adler-Bell-Jackiw Anomaly
Israel Weimin Sun
This is an article which intends to shake down the traditional belief that the celebrated Adler-Bell-Jackiw anomaly stems from the chiral rotation non-invariance of the fermionic m…
Mathematical Melody in Quantum Anomaly via the Path Integral Approach: A Lesson from the Transverse Current Anomalies in QED
Israel Weimin Sun
I address and solve the natural problem of calculating the transverse current anomalies in quantum electrodynamics by means of the path-integral method. An explicitly divergent and…
Some remarks on the current issues in nucleon spin structure study
Israel Weimin Sun
I give some personal remarks on some current issues in the nucleon spin structure study. At an elementary level I propose a new angular momentum separation for the massless Dirac f…
Quantum Gauge Transformation, Gauge-Invariant Extension and Angular Momentum Decomposition in Abelian Higgs Model
Israel Weimin Sun
I discuss the momentum and angular momentum decomposition problem in the Abelian Higgs model. The usual gauge-invariant extension (GIE) construction is incorporated naturally into…
