Abstract

We calculate the mass and residue of the heavy spin-1/2 baryons containing two heavy h or c quarks in the framework of QCD sum rules. We use the most general form of the interpolating current in its symmetric and anti-symmetric forms with respect to the exchange of heavy quarks, to calculate the two-point correlation functions describing the baryons under consideration. A comparison of the obtained results with existing predictions from various approaches is also made. (c) 2012 Elsevier B.V. All rights reserved.
