Two loop virtual corrections to $$b\rightarrow (d,s)\ell ^+\ell ^-$$ b → ( d , s ) ℓ + ℓ - and $$c\rightarrow u\ell ^+\ell ^-$$ c → u ℓ + ℓ - for arbitrary momentum transfer
Abstract Non-factorizable two loop corrections to heavy to light flavor changing neutral current transitions due to matrix elements of current–current operators are calculated analytically for arbitrary momentum transfer. This extends previous work on $$b\rightarrow (d,s)\ell ^+\ell ^-$$ b → ( d , s...
