Measurement of branching fraction of Ds+→Ds+π0 relative to Ds+→Ds+γ

Based on 7.33 fb-1 of e+e- collision data taken at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we measure the branching fraction of $D^*_s$+ → $D^+_s$ π0 relative to that of $D^*_s$+ → $D^+_s$γ to be (6.16 ± 0.43 ± 0.18)%. The first uncertainty is statistical and th...

Description
Summary:Based on 7.33 fb-1 of e+e- collision data taken at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we measure the branching fraction of $D^*_s$+ → $D^+_s$ π0 relative to that of $D^*_s$+ → $D^+_s$γ to be (6.16 ± 0.43 ± 0.18)%. The first uncertainty is statistical and the second one is systematic. By using the world average value of the branching fraction of $D^*_s$+ → $D^+_s$e+e-, we determine the branching fractions of $D^*_s$+ → $D^+_s$γ and $D^*_s$+ → $D^+_s$ π0 to be (93.57 ± 0.38 ± 0.22)% and (5.76 ± 0.38 ± 0.16)%, respectively.
