Advances in the Worldline Approach to Quantum Field Theory: Strong Fields, Amplitudes and Gravity
Filippo Fecit
This thesis is devoted to the first-quantized approach to quantum field theory, commonly known as the 'Worldline Formalism'. It collects most of the works completed by the author d…
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…
Worldline Formulations of Covariant Fracton Theories
Filippo Fecit, Davide Rovere
We develop worldline formulations of covariant fracton gauge theories. These are a one-parameter family of gauge theories of a rank-two symmetric tensor field, invariant under a sc…
The Fierz-Pauli theory on curved spacetime at one-loop and its counterterms
Leonardo Farolfi, Filippo Fecit
We compute the first four heat-kernel coefficients required for the renormalization of Linearized Massive Gravity. We focus on the Fierz-Pauli theory in a curved spacetime, describ…
Resummed effective actions and heat kernels: the Worldline approach and Yukawa assisted pair creation
Filippo Fecit, Sebastián Franchino-Viñas, Francisco D. Mazzitelli
We adapt the Worldline Formalism to obtain resummed expressions for the effective action and the heat kernel of a quantum scalar field coupled to a Yukawa background. The resummati…
Worldline path integral for the massive graviton
Filippo Fecit
We compute the counterterms necessary for the renormalization of the one-loop effective action of massive gravity from a worldline perspective. This is achieved by employing the re…
Massive gravity from a first-quantized perspective
Filippo Fecit
In this work, we investigate the BRST quantization of the massive supersymmetric spinning particle, with a twofold purpose: exploring different approaches to give m…
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…
Topological BF description of 2D accelerated chiral edge modes
Erica Bertolini, Filippo Fecit, Nicola Maggiore
We consider the topological abelian BF theory with radial boundary on a generic 3D manifold. Our aim is to study if, where and how the boundary keeps memory of the details of the b…
