Time reversal violation in K+ μ+ γ decay and three Higgs model
Abstract
Transverse muon polarization in the K+ → μ+ γ decay is calculated in the model with scalar and pseudo scalar four-Fermi interactions. Combined with a similar calculation in the K+ → μ+ π0 decay, a possible constraint on parameters in the three-Higgs model is obtained assuming sensitivity of the up-coming KEK experiment. It is pointed out that the predictions for the two polarizations are strongly correlated in the three Higgs model.
