K^L_{mu3} decay: A first evidence of Right-Handed Quark Currents ?
arXiv:hep-ph/0609272 · doi:10.1016/j.nuclphysbps.2006.12.085
Abstract
The experimental results published by KTeV and the preliminary results from NA48 concerning the slope of the Kpi scalar form factor suggest a significant discrepancy with the prediction of the Callan-Treiman low energy theorem once interpreted within the Standard Model. In this talk, we will show how this discrepancy could be explained as a first evidence of the direct coupling of right-handed quarks to W as suggested by certain type of effective electroweak theories.
