Worldline master formulas for the dressed electron propagator, part 2: On-shell amplitudes
Naser Ahmadiniaz, Victor Miguel Banda Guzman, Fiorenzo Bastianelli +3
In the first part of this series, we employed the second-order formalism and the ``symbol'' map to construct a particle path-integral representation of the electron propagator in a…
One-particle reducible contribution to the one-loop spinor propagator in a constant field
Naser Ahmadiniaz, Fiorenzo Bastianelli, Olindo Corradini +2
Extending work by Gies and Karbstein on the Euler-Heisenberg Lagrangian, it has recently been shown that the one-loop propagator of a charged scalar particle in a constant electrom…
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…
On the low energy limit of one loop photon-graviton amplitudes
F. Bastianelli, O. Corradini, J. M. Davila +1
We present first results of a systematic study of the structure of the low energy limit of the one-loop photon-graviton amplitudes induced by massive scalars and spinors. Our main…
Worldline Approach to QFT on Manifolds with Boundary
F. Bastianelli, O. Corradini, P. A. G. Pisani +1
We use the image charge method to compute the trace of the heat kernel for a scalar field on a flat manifold with boundary, representing the trace by means of a worldline path inte…
A Hierarchy of Superstrings
Fiorenzo Bastianelli, Nobuyoshi Ohta, Jens Lyng Petersen
We construct a hierarchy of supersymmetric string theories by showing that the general N-extended superstrings may be viewed as a special class of the (N+1)-extended superstrings.…
