QED effective action for an O(2)xO(3) symmetric field in the full mass range
N. Ahmadiniaz, A. Huet, A. Raya +1
An interesting class of background field configurations in QED are the O(2)xO(3) symmetric fields. Those backgrounds have some instanton-like properties and yield a one-loop effect…
Photon-Graviton Amplitudes from the Effective Action
F. Bastianelli, O. Corradini, J. M. Davila +1
We report on the status of an ongoing effort to calculate the complete one-loop low-energy effective actions in Einstein-Maxwell theory with a massive scalar or spinor loop, and to…
Three-Loop Four-Point Correlator in N=4 SYM
B. Eden, C. Schubert, E. Sokatchev
We explicitly compute the complete three-loop (O(g^4)) contribution to the four-point function of chiral primary current-like operators <(q)^2 q^2 (q)^2 q^2> in any finite N=2 SYM…
The Two-Loop Euler-Heisenberg Lagrangian in Dimensional Renormalization
Denny Fliegner, Martin Reuter, Michael G. Schmidt +1
We clarify a discrepancy between two previous calculations of the two-loop QED Euler-Heisenberg Lagrangian, both performed in proper-time regularization, by calculating this quanti…
