Abstract

By using 1.8×106 DD̄ pairs, we have measured B(D0→π-e+νe)=0.299(11)(9)%, B(D+→π0e+νe)=0.373(22)(13)%, B(D0→K-e+νe)=3.56(3)(9)%, and B(D+→K̄0e+νe)=8.53(13)(23)% and have studied the q2 dependence of the form factors. By combining our results with recent lattice calculations, we obtain |Vcd|=0.217(9)(4)(23) and |Vcs|=1.015(10)(11)(106).
