Twoloop anomalous dimensions for currents of baryons with two heavy quarks in NRQCD  
Protvino, 1998. p.13, figs. 1, refs.:22.  
We present analytical results on the twoloop anomalous dimensions of currents for baryons, containing two heavy quarks $J = [Q^{iT}C\Gamma\tau Q^j]\Gamma^{'}q^k\varepsilon_{ijk}$ with arbitrary Dirac matrices $\Gamma$ and $\Gamma^{'}$ in the framework of NRQCD in the leading order over both the relative velocity of heavy quarks and the inverse heavy quark mass. It is shown, that in this approximation the anomalous dimensions do not depend on the Dirac structure of the current under consideration.
