Title: Direct measurement of B(D{sub s}{sup +}{r_arrow}{phi}X{sup +})

Abstract

The absolute inclusive branching fraction of D{sub s}{sup +}{r_arrow}{phi}X{sup +} has been measured from data collected by the BES detector at a center-of-mass energy of 4.03 GeV, corresponding to an integrated luminosity of 22.3 pb{sup {minus}1}. At this energy, direct pair production e{sup +}e{sup {minus}}{r_arrow}D{sub s}{sup +}D{sub s}{sup {minus}} has been observed. We have selected D{sub s} candidate events by reconstructing five hadronic decay modes D{sub s}{sup +}{r_arrow}{phi}{pi}{sup +}, {bar K}{sup 0{asterisk}}K{sup +}, {bar K}{sup 0}K{sup +}, f{sub 0}{pi}{sup +} and K{sup 0}K{sup {minus}}{pi}{sup +}{pi}{sup +} and have searched for inclusive {phi}{close_quote}s in the recoiling D{sub s}{sup {minus}}. We observed three recoiling {phi}{close_quote}s in the 166.4 {plus_minus} 31.8 D{sub s} candidate events, which leads to the absolute branching fraction B(D{sub s}{sup +}{r_arrow}{phi}X{sup +})=(17.8{sub {minus}7.2}{sup +15.1}{sub {minus}6.3}{sup +0.6}) {percent} and B(D{sub s}{sup +}{r_arrow}{phi}{pi}{sup +})=(3.6{sub {minus}1.6}{sup +3.1}{sub {minus}1.3}{sup +0.4}) {percent}. {copyright} {ital 1997} {ital The American Physical Society}
