Abstract

© 2019 World Scientific Publishing Company.We calculate the mass and residue of the newly observed ωc(3000) and ωc(3066) states with quantum numbers JP = 1 2- and 3 2- within QCD sum rules. The calculation is carried out by using the general form for interpolating current for J = 1 2 baryon. Our predictions on masses are in good agreement with the experimental results.
