Anomalous Higgs Couplings at Colliders
, 1998 I summarize our results on the attainable limits on the coefficients of dimension-6 operators from the analysis of Higgs boson phenomenology using data taken at Tevatron RUNI and LEPII. Our results show that the coefficients of Higgs-vector boson couplings can be determined with unprecedented accuracy.

Anomalous Higgs Yukawa Couplings and Recent LHC Data
, 2017 Very recently, the CMS collaboration has reported a search for the production for a Standard Model (SM) Higgs boson in association with a top quark pair ($t bar{t} H$) at the LHC Run-2 and a best fit $t bar{t} H$ yield of $1.5 pm 0.5$ times the SM prediction with an observed significance of $3.3 sigma$.

Remarks on an Anomalous Triple Gauge Boson Couplings
Advances in High Energy Physics, 2021 We address the effect of an anomalous triple gauge boson couplings on a physical observable for the electroweak sector of the Standard Model, when the SU2L⊗U1Y symmetry is spontaneously broken by the Higgs mechanism to U1em.

Influence of new states in searches for negative gauge-Higgs couplings
Journal of High Energy PhysicsIn this work, we explore how constraints based on interference effects for the negative gauge-Higgs coupling scenario are affected by new physics. Models that achieve this wrong-sign gauge-Higgs coupling inevitably have new charged Higgs states.

Unitarity And Anomalous Top-Quark Yukawa Couplings
, 1994 Unitarity constraints on anomalous top-Higgs couplings are examined. We also compare the unitarity constraints with the constraints from electroweak baryogenesis and electric dipole moments derived earlier.Comment: Iowa State University Preprint, AMES ...

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.

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

Probing Anomalous Higgs Coupling through mu+ mu- --> H gamma [PDF]
, 1997 The process mu+ mu- --> H gamma, though small compared to the resonance process, could be observable at proposed muon colliders, given expected integrated luminosities. The apparently leading diagrams occur at tree-level, and are proportional to the Higgs-muon coupling.
