Learning Feynman integrals from differential equations with neural networks

Journal of High Energy Physics
We perform an exploratory study of a new approach for evaluating Feynman integrals numerically. We apply the recently-proposed framework of physics-informed deep learning to train neural networks to approximate the solution to the differential equations ...

Stabilizing the electroweak vacuum by higher dimensional operators in a Higgs-Yukawa model

, 2013
The Higgs boson discovery at the LHC with a mass of approximately 126 GeV suggests, that the electroweak vacuum of the standard model may be metastable at very high energies. However, any new physics beyond the standard model can change this picture.

Quantum properties of H → VV *: precise predictions in the SM and sensitivity to new physics

Journal of High Energy Physics
We study the quantum properties of the Higgs-boson decays into four fermions via two vector bosons (H → VV * → 4f). In particular, we focus on the case of two different-flavour lepton pairs (H → ZZ * → μ + μ − e + e − ).

Complete NLO corrections to top-quark pair production with isolated photons

Journal of High Energy Physics
We compute for the first time the so-called complete NLO corrections to top-quark pair production with one and two isolated photons in the di-lepton top-quark decay channel.

On the finite basis of two-loop ‘t Hooft-Veltman Feynman integrals

Journal of High Energy Physics
In this work, we investigate the finite basis topologies of two-loop dimensionally regularized Feynman integrals in the ‘t Hooft-Veltman scheme in the Standard Model.
