Semi-leptonic B→S decays in the standard model and in the universal extra dimension model

In this article, we assume the two nonets of scalar mesons below and above 1 GeV are all q¯q states, and study the semi-leptonic decays B→Sℓ−ν¯ℓ, B→Sℓ+ℓ− and B→Sν¯ν both in the standard model and in the universal extra dimension model using the B–S form-factors calculated by the light-cone QCD sum r...
