Feynman Integrals Meet Second-Order Partial Differential Equations
Xiang Chen, Hantian Zhang
We propose a second-order partial differential equation method to solve multi-loop Feynman integrals as an equilibrium problem. As a proof-of-concept demonstration, we perform a Ga…
Analytic two-loop electroweak corrections at high energies
Hantian Zhang
The high-energy behaviour of electroweak scattering amplitudes is of theoretical and phenomenological interest. In these proceedings, we summarize recent progress in analytic high-…
Analytic next-to-leading order electroweak corrections to Higgs boson pair production at high energies
Joshua Davies, Kay Schönwald, Matthias Steinhauser +1
We compute the complete next-to-leading order electroweak corrections to the form factors entering gluon-induced Higgs boson pair production. We consider the top quark contribution…
Physics-Informed Global Extraction of the Universal Small- Dipole Amplitude
Si-Wei Dai, Fu-Peng Li, Long-Gang Pang +4
We extract the universal small- dipole scattering amplitude from a global analysis based on a physics-informed neural network (PINN), without imposing a priori MV-typ…
Chasing the two-Higgs-doublet model via electroweak corrections at colliders
Pia Bredt, Tatsuya Banno, Marius Höfer +5
We present a comprehensive study of Higgs boson production associated with a neutrino pair at colliders () at next-to-leading-order accuracy in…
Analytic next-to-leading order Yukawa and Higgs boson self-coupling corrections to at high energies
Joshua Davies, Kay Schönwald, Matthias Steinhauser +1
We consider electroweak corrections to Higgs boson pair production, taking into account the top quark Yukawa and Higgs boson self couplings. Using differential equations we compute…
