Experiment

- What are the prospects for improving existing Xclnu/Xsgamma moment measurements ( higher order moments, lower energy cut-offs )?

Theory

- How complete are the HQE calculations in the kinetic/1S scheme? What is missing and which observables are most affected by the missing parts?

- Theory errors are dominant in the global fit. Are they overestimated in the present analyses? How can they be estimated reliably? What are their correlations?

- Clearly, the discrepancy between Vcb incl. and excl. is puzzling. How can we further test the OPE and the measurement of Vcb incl. ( new observables )?
