Abstract

Using the MILC 2+1 flavor asqtad quark action ensembles, we are calculating the form factors f₀ and f₊ for the semileptonic B_s → Kℓ v decay. A total of six ensembles with lattice spacing from ≈ 0.12 to 0.06 fm are being used. At the coarsest and finest lattice spacings, the light quark mass m'_l is one-tenth the strange quark mass m'_s. At the intermediate lattice spacing, the ratio m'_l/m'_s ranges from 0.05 to 0.2. The valence b quark is treated using the Sheikholeslami-Wohlert Wilson-clover action with the Fermilab interpretation. The other valence quarks use the asqtad action. When combined with (future) measurements from the LHCb and Belle II experiments, these calculations will provide an alternate determination of the CKM matrix element |V_ub|.
