Book excerpt: New precise measurements of D[sub s][sup+] and D*[sub s][sup+] meson production from B mesons and q[bar q] continuum events near the[Upsilon](4S) resonance are presented in this paper. Using the BABAR data recorded in 1999 and 2000 of 20.8 fb[sup -1] on-resonance and 2.6 fb[sup -1] off-resonance, we measure the inclusive branching fractions (B[yields] D[sub s][sup+])= (10.93[+-] 0.19[+-] 0.58[+-] 2.73)% and (B[yields] D*[sub s][sup+])= (7.94[+-] 0.82[+-] 0.72[+-] 1.99)%, where the first error is statistical, the second is the systematic error, and the third is the error due to the D[sub s][sup+][yields][pi][sup+] branching fraction uncertainty. The branching fractions (B[yields] D[sup (*)][sub s][sup+][bar D](*))= (5.07[+-] 0.09[+-] 0.34[+-] 1.27)% and (B[yields] D*[sub s][sup+][bar D](*))= (4.07[+-] 0.42[+-] 0.53[+-] 1.02)% have been determined from the measured D[sup (*)][sub s][sup+] momentum spectra.
