Ambiguities in the calculation of leptonic decays of excited heavy quarkonium Abstract. We point out that the determination of the leptonic decay width of radially-excited quarkonia is strongly dependent on the position of the node typical of these excitations. We suggest that this feature could be related with the longstanding ρ− π puzzle.

In supersymmetry with large tan β the decays B 0 (¯ B 0) → l + l − are dominated by the scalar and pseudoscalar Higgs penguin diagrams leading to strong enhancement of leptonic decay rates with potentially large CP asymmetries in the τ + τ − decay modes measurable in BELLE or BABAR experiments. The TAUOLA τ-lepton decay library supplemented by its universal interface can efficiently be used to ...

The two body non-leptonic Λb decays are analyzed in the HQET with factorization approximation and large Nc limit. In this limit, Λb and Λc baryons can be treated as the bound states of chiral soliton and heavy meson, and consequently the Isgur-Wise function comes out in a straight forward manner. The results obtained remain well below their previously predicted upper limit.
