Abstract. We study the potential of the measurement of the transverse muon polarization P T in the $K\to\mu\nu_\mu\gamma$ decay with a sensitivity of $\delta P_{\mathrm {T}}\sim 10^{-4}$ . It is shown that the forthcoming experiment can measure the contribution of the electromagnetic final state interactions to P T that gives a possibility to unambiguously determine the signs of the sum of the kaon form factors F V and F A even without fixing their difference. We also estimate the sensitivity of this experiment to the new physics, which could give rise to T-violation: multi-Higgs doublet models, supersymmetric extensions of the Standard Model, left-right symmetric model and leptoquark models.
