Towards the full NLO electro-weak corrections to Higgs boson pair production
Marco Bonetti, Gudrun Heinrich, Stephen Jones +4
Constraining the Higgs boson self-interaction is one of the main goals for the high luminosity phase of the LHC. A promising channel to this aim is the simultaneous production of t…
Machine Learning on Heterogeneous, Edge, and Quantum Hardware for Particle Physics (ML-HEQUPP)
Julia Gonski, Jenni Ott, Shiva Abbaszadeh +118
The next generation of particle physics experiments will face a new era of challenges in data acquisition, due to unprecedented data rates and volumes along with extreme environmen…
The structure of quark mass corrections in the amplitude at high-energy
Sebastian Jaskiewicz, Stephen Jones, Robert Szafron +1
The leading and next-to-leading order QCD predictions for Higgs boson pair production at hadron colliders suffer from a significant mass renormalisation scheme uncertainty related…
Dissecting polytopes: Landau singularities and asymptotic expansions in scattering
Einan Gardi, Franz Herzog, Stephen Jones +1
Parametric representations of Feynman integrals have a key property: many, frequently all, of the Landau singularities appear as endpoint divergences. This leads to a geometric int…
Development Framework for Longitudinal Automated Driving Functions with Off-board Information Integration
Eric Armengaud, Sebastian Frager, Stephen Jones +4
Increasingly sophisticated function development is taking place with the aim of developing efficient, safe and increasingly Automated Driving Functions. This development is possibl…

Benjamin Campillo Aveleira, Long Chen, Joshua Davies +9
We present state-of-the-art predictions for the inclusive cross section of gluon-initiated production, following the recommendations of the LHC Higgs Working Group. In particu…
Evaluating Parametric Integrals in the Minkowski Regime without Contour Deformation
Stephen Jones, Anton Olsson, Thomas Stone
We present selected examples demonstrating an alternative approach to contour deformation for numerically computing loop integrals in the Minkowski regime. This method focuses on i…

Anja Butter, Tilman Plehn, Steffen Schumann +48
First-principle simulations are at the heart of the high-energy physics research program. They link the vast data output of multi-purpose detectors with fundamental theory predicti…

Nicholas D. Morgan, George Chartas, Michael Malm +5
We present results from X-ray observations of the quadruply lensed quasar RX J0911.4+0551 using data obtained with the Advanced CCD Imaging Spectrometer (ACIS) on board the Chandra…
Globally Optimal Contour Deformations with Neural Networks
Stephen Jones, Daniel Maître, Anton Olsson
In this article, we explore the use of contour deformation for the numerical evaluation of Feynman integrals after sector decomposition. In existing codes, the contour of integrati…
The on-shell expansion: from Landau equations to the Newton polytope
Einan Gardi, Franz Herzog, Stephen Jones +2
We study the application of the method of regions to Feynman integrals with massless propagators contributing to off-shell Green's functions in Minkowski spacetime (with non-except…

Gudrun Heinrich, Stephen Jones, Matthias Kerner +2
We present results for the Yukawa-enhanced and Higgs self-coupling type electroweak corrections to di-Higgs production in gluon fusion. The calculation of the corresponding four-sc…
