Description

We study T-odd triple momentum correlations in exclusive semi-leptonic (Sl) bottom meson decays B→D*(→Dπ)+l+νl. We define asymmetry ratios that measure these T-odd triple momentum correlation effects. We provide a careful discussion of possible unitarity contributions to the asymmetry ratios. The conclusion is that strong interaction unitarity contributions are small or, in the case of one particular T-odd observable, absent. CP-violating contributions to the asymmetry ratios would have to come from new non-standard sources as there are no standard model contributions. Possible new CP-violating contributions are parametrized in terms of an effective four-fermion hamiltonian. Their effect on the T-odd asymmetry ratios are computed in terms of specific quark models describing Sl exclusive heavy meson decays. (orig.)
