15. Streamlining canonical differential equations through factorized Picard-Fuchs operators

Christoph Dlapa (University of Hamburg)

28/05/2026, 16:00

The method of differential equations has become one of the most powerful tools for the evaluation of multiloop Feynman integrals. In recent years, substantial progress has been made in extending the notion of canonical differential equations beyond the multiple polylogarithm case to integrals involving more general geometries. Nevertheless, deriving canonical forms for such systems remains...

16. Advances in quantum computation of perturbative QFT scattering

Herschel Chawdhry (Florida State University)

28/05/2026, 16:20

Perturbative QFT calculations can pose considerable computational challenges at higher orders and higher multiplicities. At the same time, the inherently quantum-mechanical nature of these calculations makes them promising candidates to exploit the qualitatively new computational capabilities of emerging quantum computing hardware. In this talk I will present recent advances in quantum...

55. $\mathcal{O}(\alpha \alpha_s^2)$ corrections to the top mass

Mr Daniele Gaggero (SUNY Buffalo)

28/05/2026, 16:40

We present the calculation of the 3-loop \mathcal{O}\alpha\alpha_s^2 corrections to the top quark mass. We discuss the evaluation of the elliptic integrals which appear as iterated solutions of a differential equation in canonical form.

72. Off-shell triphoton production via quark loops from numerical integration

Dario Kermanschah

28/05/2026, 17:00

I will give an overview of our approach for the direct numerical integration of two-loop corrections to electroweak production. After locally subtracting infrared and ultraviolet singularities, we enable numerical integration in momentum space through analytic integration over the energy components of the loop momenta, subtraction of threshold singularities, and the use of importance sampling...
