Weak K→π generalized form factors and transverse transition quark-spin density from the instanton vacuum
We investigate the generalized K→π transition vector and tensor form factors, from which we derive the transverse quark spin density in the course of the K→π transition, based on the nonlocal chiral quark model from the instanton vacuum. The results of the transition tensor form factor are in good a...
