Heavy dibaryons

The relativistic six-quark equations are found in the framework of the dispersion relation technique. The approximate solutions of these equations using the method based on the extraction of leading singularities of the heavy hexaquark amplitudes are obtained. The relativistic six-quark amplitudes of dibaryons including the light quarks $u$, $d$ and heavy quarks $c$, $b$ are calculated. The poles of these amplitudes determine the masses of charmed and bottom dibaryons with the isospins 1/2, 3/2, 5/2.
