1. SLAC

Since it began recording data in 1999, the BaBar detector at the SLAC B Factory has collected nearly 90 million B meson pairs. Using this sample, they are able to make precise measurements of B decays to open charm and charmonium. In particular, they have measured the rates for B {yields} D{bar D}K, for the color-suppressed modes B{sup 0} {yields} D{sup 0}{pi}{sup 0}, B{sup 0} {yields} D{sup 0}{eta}, and B{sup 0} {yields} D{sup 0}{omega}, for B{sup +} {yields} {chi}{sub c}{sup 0}K{sup +}, and for B{sup 0} {yields} D(*){sub s}{sup +} D*{sup -}. They have also begun preparations for a measurement of the CKM angle {gamma} by studying the modes B{sup +} {yields} D{sup 0}K{sup +}, B{sup 0} {yields} D(*){sub s}{sup +} {pi}{sup -}, and B{sup 0} {yields} D(*){sub s}{sup +} K{sup -}.
