Chiral corrections to the masses of the doubly heavy baryons

Abstract

We study the masses of the doubly bottom baryons and the charmed bottom baryons up to $\mathcal{O}\left(p^3\right)$ in heavy baryon chiral perturbation theory. For the low-energy constants, $g_A$ was determined in the quark model, and we fit to the lattice QCD data to determine $m_0$, $c_1$, and $c_7$. We show the numerical results up to $\mathcal{O}\left(p^3\right)$, and our results are compared with other theoretical results.
