Kμ3L decay: A stringent test of right-handed quark currents

Preprint, Article English OPEN
Bernard, Véronique; Oertel, Micaela; Passemar, Emilie; Stern, Jan;

Clean tests of a small admixture of right-handed quark currents directly coupled to the standard W are still lacking. We show that such non-standard couplings can be significantly constrained measuring the value of the scalar Kpi form factor at the Callan-Treiman point ... View more
