Direct measurement of B ( D 0 → φ X 0 ) and B ( D + → φ X + )

The first measurement of B(D{sup 0}{yields}{phi}X{sup 0}) and an upper limit for B(D{sup +}{yields}{phi}X{sup +}) are determined from 22.3 pb{sup -1} of e{sup +}e{sup -} annihilation data at a c.m. energy of 4.03 GeV. The data were recorded by the Beijing Spectrometer (BES) at BEPC. A recoil charge...

Zusammenfassung:	The first measurement of B(D{sup 0}{yields}{phi}X{sup 0}) and an upper limit for B(D{sup +}{yields}{phi}X{sup +}) are determined from 22.3 pb{sup -1} of e{sup +}e{sup -} annihilation data at a c.m. energy of 4.03 GeV. The data were recorded by the Beijing Spectrometer (BES) at BEPC. A recoil charge method is applied to charm threshold data to determine the charge of the D meson in the recoil from 9054{+-}309{+-}416 reconstructed D{sup 0}, D{sup +} mesons. The branching fractions B(D{sup 0}{yields}{phi}X{sup 0})=(1.71{sub -0.71}{sup +0.76}{+-}0.17)%, and B(D{sup +}{yields}{phi}X{sup +})
