Towards mixed QCDxEW corrections to the charged-current Drell-Yan process with leptonic decay at high transverse masses
Christian Biello, Amlan Chakraborty, Giulio Gambuti +2
The Drell-Yan process is a key precision benchmark at the Large Hadron Collider and a sensitive probe of SM and SMEFT effects. Fully exploiting future LHC data requires percent-lev…
Analytic results for heavy-quark contributions to charged-current DIS at NNLO
Fabrizio Caola, Giulio Gambuti, Martin Link
We present analytic results for the next-to-next-to-leading-order QCD corrections to heavy-quark production in charged-current deep-inelastic scattering, retaining the exact depend…
Light-by-light scattering at three loops in massless QCD and QED: amplitudes and cross sections
Piotr Bargiela, Amlan Chakraborty, Giulio Gambuti +1
We present the calculation of three-loop massless QCD and QED helicity amplitudes for light-by-light scattering. We make use of Lorentz tensor decomposition in the 't Hooft-Veltman…
Soft Factorisation and Exponentiation from Schwinger-Space Geometry
Carolina Figueiredo, Giulio Gambuti, Holmfridur S. Hannesdottir
Infrared divergences in Quantum Field Theory govern the low-energy dynamics of many physical theories, and their understanding is a crucial ingredient in predicting the outcomes of…
Investigating the universality of five-point QCD scattering amplitudes at high energy
Federico Buccioni, Fabrizio Caola, Federica Devoto +1
We investigate QCD scattering amplitudes in multi-Regge kinematics, i.e. where the final partons are strongly ordered in rapidity. In this regime amplitudes exhibit intri…
Five-Parton Scattering in QCD at Two Loops
Bakul Agarwal, Federico Buccioni, Federica Devoto +3
We compute all helicity amplitudes for the scattering of five partons in two-loop QCD in all the relevant flavor configurations, retaining all contributing color structures. We emp…
Finite Feynman Integrals
Giulio Gambuti, David A. Kosower, Pavel P. Novichkov +1
We describe an algorithm to organize Feynman integrals in terms of their infrared properties. Our approach builds upon the theory of Landau singularities, which we use to classify…
Three-loop helicity amplitudes for photon+jet production
Piotr Bargiela, Amlan Chakraborty, Giulio Gambuti
We present three-loop helicity amplitudes for the production of a single photon in association with one jet in Quantum Chromodynamics, a final state which provides a standard candl…
Three-Loop Four-Point Scattering Amplitudes in Massless Gauge Theories
Amlan Chakraborty, Giulio Gambuti
We present novel techniques for the computation of three-loop four-parton scattering amplitudes in full color, non-planar gauge theories. We elaborate on how the analytic results f…
Three-loop helicity amplitudes for quark-gluon scattering in QCD
Fabrizio Caola, Amlan Chakraborty, Giulio Gambuti +2
We compute the three-loop helicity amplitudes for and its crossed partonic channels, in massless QCD. Our analytical results provide a non-trivial check of the co…
Three-loop gluon scattering in QCD and the gluon Regge trajectory
Fabrizio Caola, Amlan Chakraborty, Giulio Gambuti +2
We compute the three-loop helicity amplitudes for the scattering of four gluons in QCD. We employ projectors in the 't Hooft-Veltman scheme and construct the amplitudes from a mini…
Three-loop helicity amplitudes for four-quark scattering in massless QCD
Fabrizio Caola, Amlan Chakraborty, Giulio Gambuti +2
We compute the three-loop corrections to the helicity amplitudes for scattering in massless QCD. In the Lorentz decomposition of the scattering amplitude we…
