Hadronic decays of the D{sub s} meson and a model-independent determination of the branching fraction for the D{sub s} decay of to Phi Pi

Description

During the running periods of the years 1992, 1993, 1994 the BES experiment at the Beijing Electron Positron Collider (BEPC) collected 22.9 {plus_minus} 0.7 pb{sup {minus}1} of data at an energy of 4.03 GeV, which corresponds to a local peak for e{sup +}e{sup {minus}} {yields} D{sub s}{sup +}D{sub s}{sup {minus}} production. Four D{sub s} hadronic decay modes were tagged: D{sub s} {yields} {phi}{pi}; {phi} {yields} K{sup +}K{sup {minus}}; D{sub s} {yields} {bar K}*(892){sup o}K; {bar K}*{sup o}(892) {yields} K{sup {minus}}{pi}{sup +}; D{sub s} {bar K}{sup o}K; {bar K}{sub s}{sup o} {yields} {pi}{sup +}{pi}{sup {minus}}; D{sub s} {yields} {bar K}*(892){sup o}K*; ... continued below

Description

During the running periods of the years 1992, 1993, 1994 the BES experiment at the Beijing Electron Positron Collider (BEPC) collected 22.9 {plus_minus} 0.7 pb{sup {minus}1} of data at an energy of 4.03 GeV, which corresponds to a local peak for e{sup +}e{sup {minus}} {yields} D{sub s}{sup +}D{sub s}{sup {minus}} production. Four D{sub s} hadronic decay modes were tagged: D{sub s} {yields} {phi}{pi}; {phi} {yields} K{sup +}K{sup {minus}}; D{sub s} {yields} {bar K}*(892){sup o}K; {bar K}*{sup o}(892) {yields} K{sup {minus}}{pi}{sup +}; D{sub s} {bar K}{sup o}K; {bar K}{sub s}{sup o} {yields} {pi}{sup +}{pi}{sup {minus}}; D{sub s} {yields} {bar K}*(892){sup o}K*; {bar K}*{sup o}(892) {yields} K{sup {minus}}{pi}{sup +}; K*(892) {yields} K{sup o}{pi}{sup +}; K{sub s}{sup o} {yields} {pi}{sup +}{pi}{sup {minus}}. Using the method of double-tagging, BES performed the first model-independent measurement of BrD{sub s {yields} {phi}{pi}}. Our result was Br{sub D{sub s} {yields} {phi}{pi}} = 3.4{sub {minus}1.7-0.7}{sup +4.8+1.3}
