Higgs Boson Pair Production via Gluon Fusion: Higher-Order Corrections and Theoretical Uncertainties
Ajjath A H, Simone Alioli, Emanuele Bagnaschi +51
In this contribution, the higher-order QCD and electroweak corrections to Standard Model Higgs boson pair production via the gluon-fusion mechanism, , are summarized and…
Accelerating Feynman Integral Evaluation by Avoiding Contour Deformation
Stephen P. Jones, Anton Olsson, Thomas Stone
We describe our method for rewriting dimensionally regulated Feynman parameter integrals in the Minkowski regime as a sum of real, positive integrands multiplied by complex prefact…
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…
Positive Integrands from Feynman Integrals in the Minkowski Regime
Stephen Jones, Anton Olsson, Thomas Stone
We present a method for rewriting dimensionally regulated Feynman parameter integrals in the Minkowski regime as a sum of real, positive integrands multiplied by complex prefactors…
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…
Electroweak corrections to Higgs boson pair production: The top-Yukawa and self-coupling contributions
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…
