Description
Doubly-heavy baryons, whose dynamics is determined by a light quark sutuated in a color field of a static pair of heavy quarks, are investigated. Non-local interpolation currents are introduced and corresponding matrix elements between the baryon and vacuum state are expressed in terms of light-cone distribution amplitudes. Model functions for baryon distribution amplitudes are suggested and their scale dependence is studied in the pertubative QCD framework. The similarity between the heavy meson and doubly-heavy baryon disribution amplitudes is discussed.
