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.

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 ...

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,113,/ and (3, 2, 1/6), respectively. It is found that these Leptoquarks generate a sizable transition magnetic moment, particularly when the quark bottom is ...

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.

Anomalous Higgs-top coupling pollution of the triple Higgs coupling extraction at a future high-luminosity electron-positron collider [PDF]
Physical Review D, 2015 One of the most challenging tasks for future high-luminosity electron-positron colliders is to extract Higgs triple coupling. It was proposed that this can be carried out via the precisely measuring the cross section of ZH associated production up to $0.4\%$. In this paper, we example the possible heavy pollution from Higgs-top anomalous coupling.

Annalen der Physik, Volume 537, Issue 12, December 2025.A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

de Sitter Excited State in Heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ Theory
Fortschritte der Physik, Volume 73, Issue 12, December 2025.Abstract A novel duality sequence is devised to study late‐time cosmology in the heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ setup of Horava and Witten with dynamical walls that are moving towards each other. Remarkably, the dimensionally reduced 4‐dimensional theory does not violate NEC and no bouncing or ekpyrotic phase is observed.

Search for anomalous couplings in the Higgs sector at LEP [PDF]
, 2019 We search for a Higgs particle with anomalous couplings in the eqeyaHg, eqeyaHZ and eqeyaHeqey processes with the L3 detector at LEP. We explore the mass range 70 GeV-m -170 GeV using 176 pby1 H of integrated luminosity at a center-of-mass energy of 's ...

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.
