Nucleon axial radius
Yi Chen, Yang Li, Cédric Lorcé +1
We present the first systematic study of the relativistic axial-vector four-current distributions inside a nucleon. We show in particular that the slope of the axial form factor $G…

Perturbative results of matrix elements of the axial current and their relation with the axial anomaly
Ignacio Castelli, Adam Freese, Cédric Lorcé +3
In the Standard Model of particle physics, the axial current is not conserved, due both to fermion masses and to the axial anomaly. Using perturbative quantum chromodynamics, we ca…
