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…
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…
Design and Biomechanical Evaluation of a Lightweight Low-Complexity Soft Bilateral Ankle Exoskeleton
Josée Mallah, Zakii Javed, Zafer Azak +2
Many people could benefit from exoskeleton assistance during gait, for either medical or nonmedical purposes. But exoskeletons bring added mass and structure, which in turn require…
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…
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…
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…
