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

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.

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.

The on-shell expansion: from Landau equations to the Newton polytope
Journal of High Energy Physics, 2023 We study the application of the method of regions to Feynman integrals with massless propagators contributing to off-shell Green’s functions in Minkowski spacetime (with non-exceptional momenta) around vanishing external masses, p i 2 → 0 $$ {p}_i^2\to 0

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 ...

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

Gluon-initiated associated production boosts Higgs physics [PDF]
, 2013 Analyses of boosted Higgs bosons from associated production comprise some of the main search channels for the Higgs boson at the LHC. The gluon-initiated gg→hZ subprocess has largely been ignored in phenomenological analyses of boosted associated ...

Higgs diphoton rate enhancement from supersymmetric physics beyond the MSSM
, 2012 We show that supersymmetric "new physics" beyond the MSSM can naturally accommodate a Higgs mass near 126 GeV and enhance the signal rate in the Higgs to diphoton channel, while the signal rates in all the other Higgs decay channels coincide with ...

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 ...

The Higgs trilinear coupling and the scale of new physics [PDF]
Journal of High Energy Physics, 2019 We consider modifications of the Higgs potential due to new physics at high energy scales. These upset delicate cancellations predicted by the Standard Model for processes involving Higgs bosons and longitudinal gauge bosons, and lead to a breakdown of ...
