Abstract

The mass and residues of the first radial and orbital excitations of J = 1/2 baryons containing two heavy quarks (b or c) are calculated within the QCD sum rules method. In calculations, the general forms of the interpolating currents with symmetric and anti-symmetric forms with respect to the exchange of heavy quarks have been used. Our results on the spectroscopic parameters of doubly heavy baryons are compared with the predictions of other theoretical approaches. (C) 2019 Elsevier B.V. All rights reserved.
