Mass corrections in J/ψ B B decay and the role of distribution amplitudes
Francesco Murgia, Maurizio Melis
Abstract
We consider mass correction effects on the polar angular distribution of a baryon--antibaryon pair created in the chain decay process e-e+ J/ψ B B, generalizing a previous analysis of Carimalo. We show the relevance of the features of the baryon distribution amplitudes and estimate the electromagnetic corrections to the QCD results.
