Description
In this work we have studied the pole locations of the quark propagator
by the solution of quark Dyson Schwinger equation (DSE) in term of the
truncation. We have fitted the Rainbow ladder solution (RL) of the quark
DSE with the Qin-Chang interaction on the real axis (p 2 > 0) and simul-
taneously the solution on the complex parabola with the same interaction.
The fits were made using the well known complex conjugate mass pole
parametrization and we will show that the pole locations changes quite a
bit. In addition, we will show how the pole locations change when we go
beyond the RL truncation.
