Gravitational Compton scattering at the fifth post-Minkowskian order
Giacomo Brunello, Mario Meo, Sid Smith
Working in the Worldline Quantum Field Theory framework, we obtain the classical gravitational Compton amplitude through the fifth post-Minkowskian order, . At th…
Gravitational Compton scattering at the fourth post-Minkowskian order
Giacomo Brunello, Mario Meo, Sid Smith
We compute the classical gravitational Compton amplitude at the fourth post-Minkowskian order, , within the Worldline Quantum Field Theory framework. We derive th…
All-order structure of static gravitational interactions and the seventh post-Newtonian potential
Giacomo Brunello, Manoj K. Mandal, Pierpaolo Mastrolia +4
We present a closed formula for the computation of static post-Newtonian corrections to the two-body gravitational dynamics at any odd order, assuming the lower-order results are k…
Six-loop gravitational interactions at the sixth post-Newtonian order
Giacomo Brunello, Manoj K. Mandal, Pierpaolo Mastrolia +6
We compute the gravitational interaction of two coalescing compact objects at sixth post-Newtonian order in the static limit, employing the diagrammatic approach within the effecti…
Analytic One-loop Scattering Waveform in General Relativity
Giacomo Brunello, Stefano De Angelis, David A. Kosower
Leveraging the computational framework presented in reference [JHEP 07, 062 (2024)], we evaluate the analytic scattering waveform in General Relativity to second order, $G^3 M^3 /r…
Gravitational waveforms from restriction theory and rapid-decay homology
Giacomo Brunello, Vsevolod Chestnov, Giulio Crisanti +2
We present a systematic framework for computing frequency-domain gravitational waveforms from relativistic binary scattering in different asymptotic regimes. The method yields a co…
High-energy evolution in planar QCD to three loops: the non-conformal contribution
Giacomo Brunello, Simon Caron-Huot, Giulio Crisanti +2
The Balitsky-Kovchegov (BK) equation offers a tractable description of the high-energy growth of gauge-theory scattering amplitudes and the nonlinear saturation effects that eventu…
Renormalization of effective field theories via on-shell methods: the case of axion-like particles
Luigi C. Bresciani, Giacomo Brunello, Gabriele Levati +2
We consider the most general axion-like particle effective field theory, including both CP-odd and CP-even types of interactions, and evaluate the corresponding renormalization gro…
Intersection Numbers from Companion Tensor Algebra
Giacomo Brunello, Vsevolod Chestnov, Pierpaolo Mastrolia
Twisted period integrals are ubiquitous in theoretical physics and mathematics, where they inhabit a finite-dimensional vector space governed by an inner product known as the inter…
On one-loop corrections to the Bunch-Davies wavefunction of the universe
Paolo Benincasa, Giacomo Brunello, Manoj K. Mandal +2
Understanding the loop corrections to cosmological observables is of paramount importance for having control on the quantum consistency of a theory in an expanding universe as well…
An Improved Framework for Computing Waveforms
Giacomo Brunello, Stefano De Angelis
We combine the observable-based formalism (KMOC), the analytic properties of the scattering amplitude, generalised unitarity and the heavy-mass expansion with a newly introduced IB…
Intersection Numbers, Polynomial Division and Relative Cohomology
Giacomo Brunello, Vsevolod Chestnov, Giulio Crisanti +3
We present a simplification of the recursive algorithm for the evaluation of intersection numbers for differential -forms, by combining the advantages emerging from the choice o…
Fourier Calculus from Intersection Theory
Giacomo Brunello, Giulio Crisanti, Mathieu Giroux +2
Building on recent advances in studying the co-homological properties of Feynman integrals, we apply intersection theory to the computation of Fourier integrals. We discuss applica…
Effective Field Theory Approach to General Relativity and Feynman Diagrams for Coalescing Binary Systems
Giacomo Brunello
In this thesis we elaborate on two different aspects of the Effective Field Theory (EFT) approach to a Binary Coalescing system in General Relativity (GR). First, we consider the i…
