Two-loop master integrals for the planar QCD massive corrections to di-photon and di-jet hadro-production

open access: yesJournal of High Energy Physics, 2018
We present the analytic calculation of the Master Integrals necessary to compute the planar massive QCD corrections to Di-photon (and Di-jet) production at hadron colliders. The master integrals are evaluated by means of the differential equations method

Search for supersymmetry at √s= 8 TeV in final states with jets and two same-sign leptons or three leptons with the ATLAS detector [PDF]

open access: yes, 2014
A search for strongly produced supersymmetric particles is conducted using signatures involving multiple energetic jets and either two isolated leptons (e or μ) with the same electric charge, or at least three isolated leptons.

Master integrals for the NNLO virtual corrections to q q ¯ → t t ¯ $$ q\overline{q}\to t\overline{t} $$ scattering in QCD: the non-planar graphs

open access: yesJournal of High Energy Physics, 2019
We complete the analytic evaluation of the master integrals for the two-loop non-planar box diagrams contributing to the top-pair production in the quark-initiated channel, at next-to-next-to-leading order in QCD.

Constructing d-log integrands and computing master integrals for three-loop four-particle scattering

open access: yesJournal of High Energy Physics, 2020
We compute all master integrals for massless three-loop four-particle scattering amplitudes required for processes like di-jet or di-photon production at the LHC.

From dimensional regularization to NLO computations in four dimensions

open access: yes, 2015
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.

Search for supersymmetry in events with large missing transverse momentum, jets, and at least one tau lepton in 20 fb−1 of √s = 8 TeV proton-proton collision data with the ATLAS detector [PDF]

open access: yes, 2014
A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons (electron/muon), has been performed using 20.3fb−1 of proton-proton collision

Two-loop perturbative corrections to the constrained effective potential in thermal QCD

open access: yesJournal of High Energy Physics, 2019
In this paper, we compute the constrained QCD effective potential up to two-loop order with finite quark mass and chemical potential. We present the explicit calculations by using the double line notation and analytical expressions for massless quarks ...

Two-loop splitting in double parton distributions: the colour non-singlet case

open access: yesJournal of High Energy Physics, 2021
At small inter-parton distances, double parton distributions receive their dominant contribution from the splitting of a single parton. We compute this mechanism at next-to-leading order in perturbation theory for all colour configurations of the ...
