HIGGS PHYSICS AND CP VIOLAITION [PDF]

open access: yesHigh Energy Physics, 2005
The CP violation in $K$ and B decays are discussed with the emphasize on the precise prediction for $ε'/ε$ 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.

Infrared singularities of QCD scattering amplitudes in the Regge limit to all orders

open access: yesJournal of High Energy Physics, 2018
Scattering amplitudes of partons in QCD contain infrared divergences which can be resummed to all orders in terms of an anomalous dimension. Independently, in the limit of high-energy forward scattering, large logarithms of the energy can be resummed ...

The on-shell expansion: from Landau equations to the Newton polytope

open access: yesJournal 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

Higgs characterisation in the presence of theoretical uncertainties and invisible decays

open access: yesEuropean 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

Reweighting a parton shower using a neural network: the final-state case

open access: yesJournal 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 ...

One-loop central-emission vertex for two gluons in N $$ \mathcal{N} $$ = 4 super Yang-Mills theory

open access: yesJournal 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

Search for invisible decays of Higgs bosons in the vector boson fusion and associated ZH production modes [PDF]

open access: yes, 2014
A search for invisible decays of Higgs bosons is performed using the vector boson fusion and associated ZH production modes. In the ZH mode, the Z boson is required to decay to a pair of charged leptons or a bb quark pair. The searches use the 8  TeV pp
