Physics , 2000, DOI: 10.1016/S0370-2693(00)01167-9
Abstract: We calculate the transverse muon polarization in the decay $K^{\pm}\to\pi^0\mu^{\pm}\nu$ induced by the electromagnetic two-photon final-state interaction. For the central part of the Dalitz plot the typical value of this polarization is about $4\times 10^{-6}$.

Muon transverse polarization in the $K_{l2γ}$ process within the SM and three Higgs doublets Weinberg model  [PDF]
V. V. Braguta,A. A. Likhoded,A. E. Chalov
Physics , 2001,
Abstract: We consider two possible sources of the $T$-violating muon transverse polarization in the process $K^+ \to \mu^+ \nu \gamma$: electromagnetic final state interaction in the SM and contribution due to charged-Higgs exchange diagrams in the framework of the Weinberg three doublets model. It is shown that at the one-loop level of the SM the muon transverse polarization, $P_T^{SM}$, varies within $(0.0 \div 1.1 \cdot 10^{-3})$ in the Dalitz plot region. Averaged value of the muon polarization, $$, in the kinematic region of $E_\gamma \geq 20$ MeV is equal to $4.76\cdot 10^{-4}$. In the case of the model with three Higgs doublets the muon transverse polarization is calculated as a function of charged Higgs masses, imaginary part of the Yukawa coupling constants product and vacuum expectation values of the Higgs doublets. The averaged value of the transverse polarization in the Weinberg model is $ = - 6.62 \cdot 10^{-5}$. Perspectives to probe the effect caused by the charged Higgs exchange diagrams in planned kaon experiments are discussed.

Pinning down the kaon form factors in K^+ -> mu^+ nu_mu gamma decay  [PDF]
F. L. Bezrukov,D. S. Gorbunov,Yu. G. Kudenko
Physics , 2003, DOI: 10.1103/PhysRevD.67.091503
Abstract: We find that the normal muon polarization in the decay K->mu nu_mu gamma is very sensitive to the values of the kaon vector F_V and axial-vector F_A form factors. It is shown that the ongoing KEK-E246 experiment can definitely determine the signs of the sum of the form factors if their difference is fixed from other considerations. This method can also verify the form factor values and signs obtained from the K^+ -> l^+ nu_l e^+ e^- decays. A new experiment with sensitivity to the normal and transverse muon polarizations of about 10^-4 will provide a unique possibility to determine the F_V and F_A values with a few percent accuracy.

A Search for B+ to mu+ nu_mu  [PDF]
B. Aubert
Physics , 2003,
Abstract: We have performed a search for the leptonic B decay B+ --> mu+ nu_mu with data collected at the Upsilon(4S) resonance by the BABAR experiment at the PEP-II storage ring. With an integrated luminosity of approximately 81.4 fb-1 (88.4 million BBbar pairs), we find no convincing evidence for a signal and set a preliminary upper limit on the branching fraction of BR(B+ --> mu+ nu_mu) < 6.6 x 10^{-6} at the 90% confidence level.
T-Odd Correlations in pi->e nu_e gamma and pi->mu nu_mu gamma Decays  [PDF]
F. Bezrukov,D. Gorbunov
Physics , 2002, DOI: 10.1103/PhysRevD.66.054012
Abstract: The transverse lepton polarization asymmetry in pi_l2gamma decays may probe T-violating interactions beyond the Standard Model. Dalitz plot distributions of the expected effects are presented and compared to the contribution from the Standard Model final state interactions. We give an example of a phenomenologically viable model, where a considerable contribution to the transverse lepton polarization asymmetry arises.
