Workshop on B decay into D** and related issues

Programme Scientifique

Role of the broad D** resonances in

• - semi-leptonic B-> [D**, D*π, Dππ] l ν
• - hadronic B-> [D**, D*π, Dπ] π

The form factors for B->D**

• - Theoretical model computation (sum-rule, lattice etc)
• - Experimental situation
• - Comparison (contributions from radial excitation, correction from infinit-mass-limit)

How to improve the theoretical computation of B-> D** form factor by lattice

• - Issues in the spectrum computations (cut-off effects from charm quark, multi-hadron states with slow pion)
• - B-> D** form factor at static limit of HQET
• - Lattice computation of B-> D*2 and D*0 (new parameterization)
