Claims

C1strongest claim

The sum rules for these form factors describing the Ξ*bb→Ξbγ decay are derived at q²=0 point using the Ξb distribution amplitudes. The results of the form factors are employed to calculate the corresponding decay width.

C2weakest assumption

The light cone QCD sum rules approach and the input Ξb distribution amplitudes accurately capture the non-perturbative QCD dynamics of this transition at q²=0.

C3one line summary

Light cone QCD sum rules produce the form factors T1V(q²=0), T2V(q²=0), T1A(q²=0), T2A(q²=0) for Ξ*bb → Ξb γ, from which the decay width is calculated.
