Sigma terms in Pion Weak-production near Threshold by Charged Current
We investigated pion production by charged weak current, which comprises vector and axial vector current. In particular, the contribution by the axial vector current is detailed at the pion threshold in terms of multipole amplitudes, which are useful tools for understanding the pion weak-production...
