Abstract

We provide a check of the accuracy of the auxiliary field formalism used to derive the effective Hamiltonian for baryons in the field correlator method. To this end we compare the solutions for the effective Hamiltonian with those obtained from the solution of the spinless Salpeter equation. Comparing these results gives a first estimate of the systematic uncertainty due to the use of the auxiliary field formalism for baryons.
