Deep learning to improve the sensitivity of Di-Higgs searches in the 4b channel

open access: yesJournal of High Energy Physics
The study of di-Higgs events, both resonant and non-resonant, plays a crucial role in understanding the fundamental interactions of the Higgs boson.

NLO electroweak corrections in extended Higgs sectors with RECOLA2

open access: yesJournal of High Energy Physics, 2017
We present the computer code RECOLA2 along with the first NLO electroweak corrections to Higgs production in vector-boson fusion and updated results for Higgs strahlung in the Two-Higgs-Doublet Model and Higgs-Singlet extension of the Standard Model.

Constraint on the total width of the Higgs boson from Higgs boson and four-top-quark measurements in pp collisions at s = 13 TeV with the ATLAS detector

open access: yesPhysics Letters B
This Letter presents a constraint on the total width of the Higgs boson (ΓH) using a combined measurement of on-shell Higgs boson production and the production of four top quarks, which involves contributions from off-shell Higgs boson-mediated processes.

Reconstruction of boosted and resolved multi-Higgs-boson events with symmetry-preserving attention networks

open access: yesJournal of High Energy Physics
The production of multiple Higgs bosons at the CERN LHC provides a direct way to measure the trilinear and quartic Higgs self-interaction strengths as well as potential access to beyond the standard model effects that can enhance production at large ...

Analytic approximations of 2 → 2 processes with massive internal particles

open access: yesJournal of High Energy Physics, 2023
We consider two-loop corrections to 2 → 2 scattering processes with massive particles in the final state and massive particles in the loop. We discuss the combination of analytic expansions in the high-energy limit and for small Mandelstam variable t ...

Constraints on the quartic Higgs self-coupling from double-Higgs production at future hadron colliders

open access: yesJournal of High Energy Physics, 2019
We study the indirect constraints on the quartic Higgs self-coupling that arise from double-Higgs production at future hadron colliders. To this purpose, we calculate the two-loop contributions to the gg → hh amplitudes that involve a modified h 4 vertex.

Anomalous Higgs boson production and decay [PDF]

open access: yesPhysics Letters B, 1993
A non-standard symmetry breaking sector may lead to derivative couplings of the Higgs boson and thereby to anomalous interactions with the electroweak gauge bosons. In the framework of gauge-invariant effective Lagrangians the resulting changes in Higgs boson production and decay mechanisms are related to anomalous triple vector boson couplings.

Higgs pair production at NLO QCD for CP-violating Higgs sectors

open access: yesNuclear Physics B, 2017
Higgs pair production through gluon fusion is an important process at the LHC to test the dynamics underlying electroweak symmetry breaking. Higgs sectors beyond the Standard Model (SM) can substantially modify this cross section through novel couplings ...
