  • Within pNRQCD we compute the masses of spin-averaged triply heavy baryons using the now-available NNLO pNRQCD potentials and three-body variational approach. We focus in particular on the role of the purely three-body interaction in perturbation theory. This we find to be reasonably small and of the order 25 MeV. Our prediction for the Ωccc baryon mass is 4900(250) MeV in keeping with other approaches. We propose to search for this hitherto unobserved state at B factories by examining the end… CONTINUE READING
