Meeting minutes:

  • Lu re-circulated the skim summary and indicated the next meeting will be on 6 April at usual time.
  • Markus Prim presented the form factor problem of Belle I specialmc2010 (20 streams) regarding to B->X_u l nu, where the q^2 of B->pi l nv is incorrectly modeled in high E_l region. The new MC with a flat q^2 (can be easily re-weighted later to user-based model) is being produced, and he's going to check B->rho l nv in case the same problem happens there as well.
  • Regarding to the B->pi l nv MC problem, Kevin indicated there is a existing B->pi^{+/0} l nv MC sample (4 million events) produced in 2014 with flat q^2 at kekcc server /group/belle/users_old/sibid/gsim/mdst/ 
  • Markus's talk was suggested to repeat in the next Belle I CKM meeting (21 March).
There are minutes attached to this event. Show them.
