Our main research interest is at the interface between new mathematical methods in quantum field theory and high-energy particle physics phenomenology. We study the mathematical structures which hide behind scattering amplitudes and Feynman diagrams, with the goal of developing new methods to study the dynamics of the Standard Model of particle physics. This will help us, among the others, to understand the details of the spontaneous symmetry breaking mechanism and the properties of the Higgs boson and, possibly, it will pave the way to discover signs of New Physics.

Abstract: In this paper, we present analytical results for the two-loop QCD corrections to the production of two partons or a photon and a parton in hadronic collisions, mediated by loops of massive quarks.…
Physical Review Letters
Abstract: We present a new class of evolution equations that govern the high-energy behavior of power-suppressed scattering amplitudes. The equations can be viewed as a renormalization group flow with respect…
Journal of High Energy Physics
Abstract: We show how a method to construct canonical differential equations for multi-loop Feynman integrals recently introduced by some of the authors can be extended to cases where the associated geometry is…

Abstract: We compute the photon self-energy to three loops in Quantum Electrodynamics. The method of differential equations for Feynman integrals and a complete ϵ-factorization of the former allow us to obtain…
Journal of High Energy Physics
Abstract: We present a computation of the one-loop QCD corrections to top-quark pair production in association with a W boson, including terms up to order ε2 in dimensional regularization. Providing a first…
Journal of High Energy Physics
Abstract: Several recent works have demonstrated the powerful algebraic simplifications that can be achieved for scattering amplitudes through a systematic grading of transcendental quantities. We develop these…
Journal of High Energy Physics
Abstract: We address the analytic computation of the two-loop scattering amplitudes for the production of two photons in parton-parton scattering, mediated by loops of heavy quarks. Due to the presence of…
Journal of High Energy Physics
Abstract: We compute the one-loop corrections to gg → up to order in the dimensional-regularization parameter. We apply the projector method to compute polarized amplitudes, which generalize massless helicity…
Physics Letters B
Abstract: The ATLAS and CMS collaborations at the LHC have recently announced evidence for the rare Higgs boson decay into a Z boson and a photon. We analyze the interference between the process gg→H→Zγ induced…
Physics Letters B
Abstract: We compute the planar three-loop Quantum Chromodynamics (QCD) corrections to the helicity amplitudes involving a vector boson V=Z,W±,γ⁎, two quarks and a gluon. These amplitudes are relevant to…
