Non-planar elliptic vertex

open access: yesJournal of High Energy Physics, 2022
We consider the problem of obtaining higher order in regularization parameter ε analytical results for master integrals with elliptics. The two commonly employed methods are provided by the use of differential equations and direct integration of ...

Measurement of the low-mass Drell-Yan differential cross section at √s = 7 TeV using the ATLAS detector [PDF]

open access: yes, 2014
The differential cross section for the process Z/γ ∗ → ℓℓ (ℓ = e, μ) as a function of dilepton invariant mass is measured in pp collisions at s√ = 7 TeV at the LHC using the ATLAS detector.

Evaluating multi-loop Feynman integrals numerically through differential equations

open access: yesJournal of High Energy Physics, 2019
The computation of Feynman integrals is often the bottleneck of multi-loop calculations. We propose and implement a new method to efficiently evaluate such integrals in the physical region through the numerical integration of a suitable set of ...

QCD static force in gradient flow

open access: yesJournal of High Energy Physics, 2022
We compute the QCD static force and potential using gradient flow at next-to-leading order in the strong coupling. The static force is the spatial derivative of the static potential: it encodes the QCD interaction at both short and long distances.

Computational framework for steady-state NLOS localization under changing ambient illumination conditions

open access: yesOptics Express, 2022
Non-line-of-sight (NLOS) imaging of hidden objects is a challenging yet vital task, facilitating important applications such as rescue operations, medical imaging, and autonomous driving. In this paper, we attempt to develop a computational steady-state NLOS localization framework that works accurately and robustly under various illumination conditions.

Muon-electron scattering at NLO

open access: yesJournal of High Energy Physics, 2019
We consider the process of muon-electron elastic scattering, which has been proposed as an ideal framework to measure the running of the electromagnetic coupling constant at space-like momenta and determine the leading-order hadronic contribution to the ...

From dimensional regularization to NLO computations in four dimensions [PDF]

open access: yesProceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2015), 2016
Loop-tree duality (LTD) allows to express virtual contributions in terms of phase-space integrals, thus leading to a direct mapping with real radiation terms. We review the basis of the method and describe its application to regularize Feynman integrals.

Master integrals for the NNLO virtual corrections to μe scattering in QED: the planar graphs

open access: yesJournal of High Energy Physics, 2017
We evaluate the master integrals for the two-loop, planar box-diagrams contributing to the elastic scattering of muons and electrons at next-to-next-to leading-order in QED.

Automation of NLO computations using the FKS subtraction method [PDF]

open access: yesProceedings of RADCOR 2009 - 9th International Symposium on Radiative Corrections (Applications of Quantum Field Theory to Phenomenology) — PoS(RADCOR2009), 2010
In this talk the FKS subtraction method for next-to-leading order (in QCD) computations is reviewed and its automation in the computer code MadFKS is presented. As a proof of concept, some results in the form of plots for distributions at next-to-leading order in e+e− → 2, 3 and 4 jets are shown by interfacing this code to BlackHat and Rocket.
