Very heavy flavored dibaryons
arXiv:2005.06894 · doi:10.1103/PhysRevLett.124.212001
Abstract
We explore the possibility of very heavy dibaryons with three charm quarks and three beauty quarks, , using a constituent model which should drive to the correct solution in the limit of hadrons made of heavy quarks. The six-body problem is treated rigorously, in particular taking into account the orbital, color and spin mixed-symmetry components of the wave function. Unlike a recent claim based on lattice QCD, no bound state is found below the lowest dissociation threshold.
