14. A model for the color suppressed decay mode B^0 --> 2 \pi^0

Prof. Jan Olav Eeg (University of Oslo)

I present a model for the color suppressed decay mode B^0 --> 2 \pi^0. The model is an extension of (heavy-light) chiral quark models. The color suppressed (nonfactorizable) decay mode is obtained in terms of a model dependent gluon condensate. The model can account for the experimental result. Unfortunately, the theoretical result obtained within the model is very sensitive to the two...

44. Status of semileptonic B decays

Paolo Gambino (Turin U and INFN)

I will review the determination of Vcb and Vub from semileptonic B decays, focussing on inclusive decays and discussing the extraction of the c and b quark masses from a theoretical point of view.

29. Threshold Resummed Mass Corrected Spectra in Heavy Quark Decays

Giulia Ricciardi (Dip. di Scienze Fisiche Univ. Napoli Federico II)

We discuss resummed formulae in semileptonic decays of a heavy quark $h$ into a quark $q$ plus a non-hadronic final state, including mass effetcs of the final quark.

8. Isgur-Wise functions and the Lorentz group

The Isgur-Wise functions are expressed in terms of scalar products of states of the light cloud in a Hilbert space, related by Lorentz transformations. This fact leads to strong constraints on their possible shape.
