ILC Higgs Physics Potential [PDF]
Proceedings of Particles and Nuclei International Conference 2021 — PoS(PANIC2021), 2022 Higgs factories based on e+e- colliders have the potential to measure the complete profile of the Higgs boson at a level of precision that goes qualitatively beyond the expect capabilities of the LHC. This talk will review the program of Higgs boson coupling measurements expected from the International Linear Collider, including the most recent updates.

Large gauge effects and the structure of amplitudes
Journal of High Energy Physics, 2023 We show that large gauge transformations modify the structure of momentum conservation leading to non-vanishing three-point amplitudes in a simple toy model of a gravitational wave event.

Challenges for MSSM Higgs searches at Hadron Colliders [PDF]
, 2007 In this article we analyze the impact of B-physics and Higgs physics at LEP on standard and non-standard Higgs bosons searches at the Tevatron and the LHC, within the framework of minimal flavor violating supersymmetric models.

HIGGS PHYSICS AND CP VIOLAITION [PDF]
High Energy Physics, 2005 The CP violation in $K$ and B decays are discussed with the emphasize on the precise prediction for $ '/ $ and the new physics effects from a class of models with additional Higgs doublets and fermions. The contributions from standard model with two-Higgs-doublet (S2HDM) to $K$, $B$ mixing and decays are briefly reviewed.

One-loop central-emission vertex for two gluons in N $$ \mathcal{N} $$ = 4 super Yang-Mills theory
Journal of High Energy Physics, 2022 A necessary ingredient for extending the BFKL equation to next-to-next-to-leading logarithmic (NNLL) accuracy is the one-loop central emission vertex (CEV) for two gluons which are not strongly ordered in rapidity. Here we consider the one-loop six-gluon

Top mass determination, Higgs inflation, and vacuum stability [PDF]
, 2014 The possibility that new physics beyond the Standard Model (SM) appears only at the Planck scale $M_P$ is often considered. However, it is usually argued that new physics interactions at $M_P$ do not affect the SM stability phase diagram, so the latter ...

Reweighting a parton shower using a neural network: the final-state case
Journal of High Energy Physics, 2019 The use of QCD calculations that include the resummation of soft-collinear logarithms via parton-shower algorithms is currently not possible in PDF fits due to the high computational cost of evaluating observables for each variation of the PDFs ...

Higgs characterisation in the presence of theoretical uncertainties and invisible decays
European Physical Journal C: Particles and Fields, 2017 While the Higgs characterisation programme is well under way, direct signs for new physics beyond the Standard Model remain elusive. Performing a fit of fully differential Higgs production cross sections at the LHC to a subset of Higgs-relevant effective

Towards the ultimate SM fit to close in on Higgs physics [PDF]
, 2013 A bstractWith the discovery of the Higgs at the LHC, experiments have finally addressed all aspects of the Standard Model (SM). At this stage, it is important to understand which windows for beyond the SM (BSM) physics are still open, and which are ...

Wave scattering event shapes at high energies
Journal of High Energy Physics, 2023 We study the space and properties of global and local observables for radiation emitted in the scattering of a massive scalar field in gauge and gravitational plane-wave backgrounds, in both the quantum and classical theory. We first compute the radiated
