Re-analysis of rare radiative ${\Xi }_b^{-}\to {\Xi }^{-}\gamma$ decay in QCD

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

The upper limit of the branching ratio of the rare ${\Xi }_b^{-}\to {\Xi }^{-}\gamma$ decay is obtained as $BR({\Xi }_b^{-}\to {\Xi }^{-}\gamma )<1.3\times 10^{-4}$ by the LHCb. In the present work we s…
