Helicity Analysis of the Decays B → K ∗ l + l − and B → ρ l ν l in the Large Energy Effective Theory

We calculate the independent helicity amplitudes in the decays B → K∗l+l− and B → ρlνl in the so-called Large-Energy-Effective-Theory (LEET). Taking into account the dominant O(αs) and SU(3) symmetry-breaking effects, we calculate various Dalitz distributions in these decays making use of the presently available data and decay form factors calculated in the… CONTINUE READING
