Renormalization of quark axial current in the chiral potential model
X. S. Chen, X. B. Chen, Amand Faessler +2
Non-conserved composite operators like the quark axial current have divergent matrix elements therefore must be renormalized. We explore how this can be done in quark model calcula…

Positive strangeness contribution to the nucleon magnetic moment in a relativistic chiral potential model
X. B. Chen, X. S. Chen, Amand Faessler +2
The strangeness contribution to the nucleon magnetic moment is calculated at the one-loop level in a relativistic SU(3) chiral potential model and is found to be {\em positive}, th…
