| Abstract: | In three-dimensional quantum electrodynamics(QED3) with a massivegauge boson, we investigate the coupled Dyson-Schwinger equations forthe fermion and photon propagators in the rainbow approximation, andobtain the critical gauge boson mass for various numbers of the fermionflavors. A comparison with the previous results is presented. |
| Keywords: | QED3 dynamical chiral symmetry breaking critical gauge boson mass |
