One loop photon-graviton mixing in an electromagnetic field: Part 3
Naser Ahmadiniaz, Fiorenzo Bastianelli, Felix Karbstein und Christian Schubert
Photon-graviton conversion in an electromagnetic field is a well-known prediction of Einstein-Maxwell theory. First discussed at tree-level by Gertsenshtein in 1962, more recently…
Pair production of massive charged vector bosons from the worldline
Fiorenzo Bastianelli, Filippo Fecit, Alessandro Miccichè
We investigate a worldline formulation for a massive spin-1 particle interacting with an electromagnetic background. Two first-quantized descriptions of the spin degrees of freedom…
Gluon amplitudes in first quantization
Fiorenzo Bastianelli, Roberto Bonezzi, Olindo Corradini +1
We compute tree-level gluon amplitudes as worldline correlators of vertex operators in a bosonic spinning particle model. In this framework, the particle's position degrees of free…
Unified worldline treatment of Yukawa and axial couplings
F. Bastianelli, O. Corradini, J. P. Edwards +2
We provide a worldline representation of the one-loop effective action for a Dirac particle coupled to external scalar, pseudoscalar, vector and axialvector fields. Extending previ…
Six-dimensional one-loop divergences in quantum gravity from the spinning particle
Fiorenzo Bastianelli, Francesco Comberiati, Filippo Fecit +1
In this work, we investigate the computation of the counterterms necessary for the renormalization of the one-loop effective action of quantum gravity using both the worldline form…
Worldline path integrals for the graviton
Fiorenzo Bastianelli, Mattia Damia Paciarini
We present an extension to arbitrary dimensions of a worldline path integral approach to one-loop quantum gravity, which was previously formulated in four spacetime dimensions. By…
