T-odd correlation in the K+ ->pi l nu gamma decays beyond Standard Model

Abstract

The dependence of the T-odd correlation on the effective Lagrangian parameters in the $K^{+}\to \pi l\nu \gamma ,l=e,\mu$ decays is analyzed. It is shown that the introduced observable is perspective in a search for new physics in the vector and pseudovector sector of the Lagrangian. As for scalar and pseudoscalar sectors, the T-odd correlation studies will not allow one to improve current restrictions on parameters of models beyond SM.
