CP violating polarizations in semileptonic heavy meson decays
We study the -violating lepton transverse polarization () in
three body semileptonic heavy meson decays to pseudoscalar mesons and to vector
mesons. We calculate these polarizations in the heavy quark effective limit,
which simplifies the expressions considerably. After examining constraints from
conserving (including ) and violating
processes, we find that in decays, of the muon in multi-Higgs
doublet models can be of order , while of the can even
approach unity. In contrast, in decays is at most 1.5\%. We
discuss possibilities for detection of at current and future
factories. We also show that in decays to vector mesons, unlike in
decays to pseudoscalars, can get contributions from left-right models.
Unfortunately, in that case is proportional to - mixing,
and is thus small.Comment: 32pp plain LATEX, 3 figs (by EMAIL request), TRI-PP-94-1
