This decay proceeds through the flavor changing neutral current $b\\to s$ transition in the Standard Model. The hadronic matrix element of the considered decay is parameterized in terms of four tensor form factors $T_1^{V}(q^2)$, $T_2^{V}(q^2)$, $T_1^{A}(q^2)$ and $T_2^{A}(q^2)$. The sum rules for these form factors describing the $\\Xi^{*}_{bb}\\to\\Xi_b\\gamma$ decay are derived at $q^2=0$ point using the $\\Xi_b$ distribution amplitudes.
