Measurement of branching fraction of D-s*+ -> D-s(+)pi(0) relative to D-s*+ -> D-s(+)gamma

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(+)pi(0) relative to that of D-s*(+) -> D-s(+)gamma to be (6.16 +/- 10.43 +/- 10.18)%. 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(+)gamma and D-s(*+) -> D-s(+)pi(0) to be (93.57 +/- 10.38 +/- 10.22)% and (5.76 +/- 10.38 +/- 10.16)%, respectively.

Automated summary

Based on the data from e(+)e(-) collisions at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, the branching fraction of D-s*(+)-> D-s(+)pi(0) relative to that of D-s*(+) -> D-s(+)gamma is measured to be (6.16 +/- 10.43 +/- 10.18)%. The statistical and systematic uncertainties are taken into account. Using the world average value of the branching fraction of D-s*(+) -> D-s(+) e(+)e(-), the branching fractions of D-s(*+) -> D-s(+)gamma and D-s(*+) -> D-s(+)pi(0) are determined to be (93.57 +/- 10.38 +/- 10.22)% and (5.76 +/- 10.38 +/- 10.16)%, respectively.
