Abstract:
|
The divergence of the photon self-energy diagram in spinor quantum electrodynamics in $(2+1)$ dimensional space time- $(QED_2)$ is studied by the Pauli-Villars regularization and dimensional regularization. Results obtained by two different methods are coincided if the gauge invariant of theory is considered carefully step by step in these calculations. |
