Next-to-leading-logarithm kT resummation for Bc → J/ψ decays
We derive the kT resummation for a transverse-momentum-dependent charmonium wave function, which involves the bottom quark mass mb, the charm quark mass mc, and the charm quark transverse momentum kT, up to the next-to-leading-logarithm (NLL) accuracy under the hierarchy mb≫mc≫kT. The resultant Suda...
