Doubly heavy systems: decays and OPE
Andrei I. Onishchenko
We discuss questions related to the application of OPE for the long-lived systems with two heavy flavors. The values of quark masses entering such calulations are constrained by us…
Doubly heavy baryons in sum rules of NRQCD
V. V. Kiselev, A. I. Onishchenko
The masses of baryons containing two heavy quarks and their couplings to the corresponding quark currents are evaluated in the framework of NRQCD sum rules. The coulomb-like correc…
Semileptonic B_c-meson decays in sum rules of QCD and NRQCD
V. V. Kiselev, A. K. Likhoded, A. I. Onishchenko
The semileptonic B_c-meson decays into the heavy quarkonia J/ψ(η_c) and a pair of leptons are investigated in the framework of three-point sum rules of QCD and NRQCD. Calculations…
Lifetimes of Xi_{bc}^{+} and Xi_{bc}^{0} baryons
V. V. Kiselev, A. K. Likhoded, A. I. Onishchenko
Estimates of lifetimes and partial branching ratios for the baryons and are presented using the inverse heavy quark mass expansion technique carried out i…
