One-loop corrections to the two-body decays of the neutral Higgs bosons in the complex NMSSM

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Since no direct signs of new physics have been observed so far indirect searches in the Higgs sector have become increasingly important. With the discovered Higgs boson behaving very standard model (SM)-like, however, indirect new physics manifestations ...

Off-shell Higgs couplings in H⁎ → ZZ → ℓℓνν

open access: yesPhysics Letters B, 2021
We explore the new physics reach for the off-shell Higgs boson measurement in the pp→H⁎→Z(ℓ+ℓ−)Z(νν¯) channel at the high-luminosity LHC. The new physics sensitivity is parametrized in terms of the Higgs boson width, effective field theory framework, and

Finite quark-mass effects in Higgs boson production with dijets at large energies

open access: yesJournal of High Energy Physics, 2019
The production of a Higgs boson in association with at least two jets receives contributions both from the fusion of weak vector bosons (VBF) and from QCD processes, especially gluon fusion (GF). The former process is important for measuring the coupling

Higher partial wave contamination in finite-volume 1-to-2 transitions

open access: yesJournal of High Energy Physics
In their seminal work, Lellouch and Lüscher derived a conversion factor relating a finite-volume matrix element, calculable using numerical lattice QCD, with the infinite-volume decay amplitude for K → ππ.

The scale of new physics from the Higgs couplings to gg

open access: yesPhysics Letters B, 2022
Measuring the Higgs couplings accurately at colliders is one of the best routes for finding physics Beyond the Standard Model (BSM). If the measured couplings deviate from the SM predictions, then this would give rise to energy-growing processes that ...

Structure-dependent QED in B − → ℓ − ν ¯ γ $$ {B}^{-}\to {\ell}^{-}\overline{\nu}\left(\gamma \right) $$

open access: yesJournal of High Energy Physics
Based on explicitly gauge invariant interpolating operators we compute complete next-leading order QED-corrections for leptonic decays. These are sizeable since the helicity-suppression in V-A interactions allows for structure-dependent collinear logs ...
