Description
The HQET Lagrangian containing the non-perturbative parameters ($\overline{\Lambda}$, $\lambda_1$, and $\lambda_2$) are studied for S-wave singly heavy baryons. The mass formulae are used to estimate these parameters for $n=1$ singly heavy charm and bottom baryons. The symmetry of these parameters is used to calculate the masses of radially excited heavy baryons. Also, the ratio of $\frac{1}{m_Q^1}$ order mass terms with the $\frac{1}{m_Q^0}$ order mass terms are varied with the heavy quark mass. This study can be expanded for orbitally excited states also.
