Abstract

Lattice calculations of the form factors for the charm semileptonic decays DπKl-and D-l provide inputs to direct determinations of the CKM matrix elements |Vcs| and |Vcd| and can be designed to validate calculations of the form factors for the bottom semileptonic decays B-l and BπKl l. We are using Fermilab charm (bottom) quarks and asqtad staggered light quarks on the 2+1 flavor asqtad MILC ensembles to calculate the charm (bottom) form factors. We outline improvements to the previous calculation of the charm form factors and detail our progress. We expect our current round of data production to allow us to reduce the theoretical uncertainties in |Vcs| and |Vcd| from 10.5% and 11%, respectively, to about 7%.
