Research Field

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.

Two-loop Feynman integrals for single top production at NNLO

Providing higher order QCD corrections to the hadronic production of top quarks at the LHC is an important step towards obtaining a more detailed understanding of electroweak symmetry breaking, due to the fact that top quarks receive their mass through interactions with the Higgs background field. Single top production is one of the most prominent top quark production channels at the LHC, with the t-channel process, which involves the production of a single top quark mediated by an exchange of a W boson, accounting for 70% of all single top quarks produced at LHC collisions. Recently, NNLO corrections to the so-called non-factorisable contributions to the single top t-channel were computed. The calculation was performed by calculating all the relevant 2-loop Feynman integrals numerically. It will be the aim of this project to provide an efficient analytic representation of these integrals in terms of special functions (e.g. multiple polylogarithms), by employing modern methods of multiloop calculations such as integration-by-part identities, canonical differential equations and the study of the relevant special functions.
