A functional approach to the next to eikonal approximation of high energy gravitational scattering
A. R. Fazio, E. A. Reyes R.
The Fradkin-Schwinger functional methods to represent a Green function in an external gravitational field are used to study the eikonal and the next-to-eikonal limit, including the…
Cosmological Correlators, In-In Formalism and Double Copy
A. R. Fazio
We are investigating if the double copy structure as product of scattering amplitudes of gauge theories applies to cosmological correlators computed in a class of theories for infl…
Comparison of the EFT Hybrid and Three-Loop Fixed-Order Calculations of the Lightest MSSM Higgs Boson Mass
E. A. Reyes R., A. R. Fazio
The lightest Higgs boson mass of the Minimal Supersymmetric Standard Model has been recently computed diagrammatically at the three-loop order in the whole supersymmetric parameter…
The Lightest Higgs Boson Mass of the MSSM at Three-Loop Accuracy
E. A. Reyes R., A. R. Fazio
In this article we provide explicit computations of the quantum corrections to the lightest CP-even Higgs Boson mass in the real version of the Minimal Supersymmetric Standard Mode…
To , or not to : Recent developments and comparisons of regularization schemes
C. Gnendiger, A. Signer, D. Stöckinger +16
We give an introduction to several regularization schemes that deal with ultraviolet and infrared singularities appearing in higher-order computations in quantum field theories. Co…
Generalised Unitarity for Dimensionally Regulated Amplitudes
W. J. Torres Bobadilla, A. R. Fazio, P. Mastrolia +1
We present a novel set of Feynman rules and generalised unitarity cut-conditions for computing one-loop amplitudes via d-dimensional integrand reduction algorithm. Our algorithm is…
