Description
In this. talk we show the current status of the B to D*lv calculation at non-zero recoil, carried out within the Fermilab and MILC collaborations. We present an overview of the calculation and we show the current preliminary results. We also emphasize some pitfalls we have encountered during the project.
Our analysis includes 15 MILC asqtad ensembles with N_f=2+1 flavors of sea quarks, and lattice spacings ranging from a=0.15 fm to a=0.045 fm. The light valence quarks use the asqtad action, whereas the heavy quarks are treated using the Fermilab action.
