Light cone QCD sum rules study of the rare radiative ${\Xi }_{bb}^{\ast }\to {\Xi }_b\gamma$ decay

T. M. Aliev, A. Ozpineci, Y. Sarac

The rare radiative decay ${\Xi }_{bb}^{\ast }\to {\Xi }_b\gamma$ is investigated within the light cone QCD sum rules approach. This decay proceeds through the flavor changing neutral current $b\to s$…
