Abstract
We present the result of the first measurement of the T-violating muon polarization PT in the decay K+ --> mu+ nu gamma. This polarization is sensitive to new sources of CP-violation in the Higgs sector. Using data accumulated in the period 1996-98 we have obtained PT = (-0.64 +- 1.85(stat) +- 0.10(syst))x10-2 which is consistent with no T-violation in this decay.
