“…The difference in the number of hits between these two counters is an asymmetry representing the transverse polarization P T of interest. 1 The matrix element (1.1) doesn't include explicitly any exotic terms, since our recent study of K + → π 0 e + ν (K + e3 ) decays shows that, first, scalar fS and tensor fT form factors are consistent with zero [2] and, second, there is no deviation from µ-e universality [3].…”

“…They gave the upper limit on the magnitude of interference between scalar S and tensor T couplings. Shimizu et al [13] determined the ratio of the strengths of scalar and tensor couplings to the standard vector coupling in K + → π 0 + e + + ν e decay at rest assuming the only lefthanded neutrinos for all interactions. Bodek et al at the PSI [14] looked for the evidence of the violation of time reversal invariance measuring T -odd transverse positron polarization in µ + -decay.…”
