摘要

The radiative decays of \({{D}_{{s1}}}{{(2536)}^{ + }}\) charmed-strange meson have not been observed. We employ the available Babar measurements to derive an upper bound for the \({{D}_{{s1}}}{{(2536)}^{ + }} \to D_{s}^{ + }\gamma \) decay width and discuss its implications for the quark structure of \({{D}_{{s1}}}{{(2460)}^{ + }}\) .
