N2 - Using 7.33 fb−1 of e+e− collision data samples collected with the BESIII detectorat center-of-mass energies between 4.128 and 4.226 GeV, we perform a search for the radiative decay D+s → γK∗(892)+ via K∗(892)+ → K+π0 and K∗(892)+ → K0Sπ + for the first time. No significant signals are observed. The upper limit on the branching fraction of D+s → γK∗(892)+ is set to be 2.3 × 10−4 at the 90% confidence level.
