Specific three-loop contributions to b → sγ associated with the current-current operators
Abstract We work out a specific class of three-loop diagrams (of order α s 2 $$ {\alpha}_s^2 $$ ) contributing to the decay amplitude for b → sγ associated with the current-current operators O 1 and O 2 at the physical value of the charm-quark mass m c . For many of the considered diagrams we were a...
