Abstract

We calculate the mass and residue of the newly observed [Formula: see text] and [Formula: see text] states with quantum numbers [Formula: see text] and [Formula: see text] within QCD sum rules. The calculation is carried out by using the general form for interpolating current for [Formula: see text] baryon. Our predictions on masses are in good agreement with the experimental results.
