Form factors for semi-leptonic B decays

Zhou, Ran, Gottlieb, Steven, Bailey, Jon A. et al.

Understand

We report on form factors for the B->K l^+ l^- semi-leptonic decay process.

We use several lattice spacings from a=0.12 fm down to 0.06 fm and a variety of dynamical quark masses with 2+1 flavors of asqtad quarks provided by the MILC Collaboration.
These ensembles allow good control of the chiral and continuum extrapolations.
The b-quark is treated as a clover quark with the Fermilab interpretation.
