Search for Tensor Interactions in Kaon Decays at DA$Φ$NE

Abstract

The semileptonic kaon decays $K_{l2γ}$ and $K_{l3}$ are considered. We use the most general forms of the matrix elements for these decays. Additional terms could arise as a result of new tensor interactions between quarks and leptons. Such terms have been detected in a recent experiments. The high precision experiments at DA$Φ$NE may be ideal to confirm these results.
