The chromomagnetic dipole operator and the B semileptonic branching ratio
We consider the possibility of having a large branching ratio for the decay b\to s g coming from an enhanced Wilson coefficient of the chromomagnetic dipole operator. We show that values of BR(b\to s g) up to \sim 10\% or more are compatible with the constraints coming from the CLEO experimental res...
