The role of long distance contribution to the B → K⁎ℓ+ℓ− in the Standard Model

We investigate rare semileptonic B→K⁎ℓ+ℓ− by looking at a specific long distance contribution. Our analysis is limited to the very small values of physical accessible range of invariant mass of the leptonic couple q2. We show that the light quarks loop has to be accounted for, along with the charmin...
