The fixed point action for the Schwinger model: a perturbative approach
F. Farchioni, V. Laliena
We compute the fixed point action of a properly defined renormalization group transformation for the Schwinger model through an expansion in the gauge field. It is local, with coup…
The fixed point action of the Schwinger model
F. Farchioni, V. Laliena
We compute the fixed point action for the Schwinger model through an expansion in the gauge field. The calculation allows a check of the locality of the action. We test its perfect…
Some O(α^2) Annihilation Type Contributions to the Orthopositronium Width
V. Antonelli, V. Ivanchenko, E. Kuraev +1
We consider some radiative corrections to the lowest order annihilation diagram for the orthopositronium decay rate. The insertion of the renormalized vertex correction in the anni…
Continuous Chiral Transition in Strongly Coupled Compact QED with the Standard Torus Topology
Vicente Azcoiti, Giuseppe Di Carlo, Angelo Galante +2
We analyze the phase diagram of compact QED on the torus with a chirally symmetric four fermion interaction added to the usual Wilson action. Inside a mean field approximation for…
