Sensitivity study of anomalous HZZ couplings at a future Higgs factory *

Chinese Physics C, 2019
Abstract We study the sensitivity of constraining the model independent H ZZ coupling based on the effective theory up to dimension-6 operators at a future Higgs factory. Using the current conceptual design parameters of the Circular Electron Positron Collider, we give the experimental limits for the model independent ...

Higgs and Top quark coupled with a conformal gauge sector

, 2007
We propose a dynamical scenario beyond the standard model, in which the radiative correction to the Higgs mass parameter is suppressed due to a large anomalous dimension induced through a conformal invariant coupling with an extra gauge sector.

Studies of Parity Violation in Atoms

Annalen der Physik, Volume 537, Issue 2, February 2025.
This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.

Note on anomalous Higgs-boson couplings in effective field theory

Physics Letters B, 2015
We propose a parametrization of anomalous Higgs-boson couplings that is both systematic and practical. It is based on the electroweak chiral Lagrangian, including a light Higgs boson, as the effective field theory (EFT) at the electroweak scale $v$. This is the appropriate framework for the case of sizeable deviations in the Higgs couplings of order ...

WWh anomalous couplings at one loop from a seesaw variant of radiatively-induced neutrino masses

Journal of High Energy Physics
After the successful measurement of the Higgs-like particle at the Large Hadron Collider, the determination of whether it corresponds to either the minimal version of the Higgs scalar, provided by the Standard Model, or to some new physics, so far ...

Exploring the Interface Between Planetary Boundaries and Palaeoecology

Global Change Biology, Volume 31, Issue 1, January 2025.
Planetary boundaries assist in delineating the ‘safe operating spaces’ beyond which critical Earth system processes could collapse. Knowledge of variability throughout the Holocene can be used in defining safe operating spaces and constraining limits of acceptable change. Palaeoecology can inform decisions about where change could be resisted, accepted

Single Higgs production at LHC as a probe for an anomalous Higgs self coupling [PDF]

Proceedings of 38th International Conference on High Energy Physics — PoS(ICHEP2016), 2017
We explore the possibility of probing the trilinear Higgs self coupling indirectly, through single Higgs production and decay processes. The method relies on the effects that electroweak loops featuring an anomalous trilinear coupling would imprint on single Higgs production at the LHC.
