| + | The abundant decay B0->D-pi+ is often used as normalization channel, given its | ||
| + | clean signal, and well-known branching fraction, as measured by the B-factories. | ||
| + | However, this branching fraction can be determined more precisely, when comparing | ||
| + | to the decay B+->D0pi+ , which has a twice better precision. | ||
| + | |||
| + | In addition, the production of B0 and B+ mesons is often assumed to be equal, | ||
| + | based on isospin symmetry. The study of B+->D0pi+ and B0->D-pi+ allows for the | ||
| + | first measurement of this ratio, fd/fu. | ||
| + | |||
| + | Our group at Nikhef has 10 years experience in the analysis of B->Dh decays. | ||
| + | This analysis may lead to a publication on behalf of the LHCb collaboration. | ||
