Analysis of the ${1\over 2}^+$ doubly heavy baryon states with QCD sum rules

Understand

In this article, we study the ${1\over 2}^+$ doubly heavy baryon states $\Omega_{QQ}$ and $\Xi_{QQ}$ by subtracting the contributions from the corresponding ${1\over 2}^-$ doubly heavy baryon states with the QCD sum rules, and make reasonable predictions for their masses.

• Those doubly heavy baryon states maybe observed at the Tevatron, the LHCb and the PANDA.
