Primary observables for indirect searches at colliders

Journal of High Energy Physics, 2023
We consider the complete set of observables for collider searches for indirect effects of new heavy physics. They consist of SU(3)C × U(1)EM invariant interaction terms/operators that parameterize deviations from the Standard Model.

Machine learning the trilinear and light-quark Yukawa couplings from Higgs pair kinematic shapes

Journal of High Energy Physics, 2022
Revealing the Higgs pair production process is the next big challenge in high energy physics. In this work, we explore the use of interpretable machine learning and cooperative game theory for extraction of the trilinear Higgs self-coupling in Higgs pair

Search for anomalous couplings in the Higgs sector at LEP [PDF]

Physics Letters B, 2000
Anomalous couplings of the Higgs boson are searched for through the processes e^+ e^- -> H gamma, e^+ e^- -> e^+ e^- H and e^+ e^- -> HZ. The mass range 70 GeV < m_H < 190 GeV is explored using 602 pb^-1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies sqrt(s)=189-209 GeV.

Positivity bounds at one-loop level: the Higgs sector

Journal of High Energy Physics, 2023
In this paper, we promote the convex cone method of positive bounds from tree level to loop level. This method is general and can be applied to obtain leading s 2 positivity bounds on the forward scattering process in the standard model effective field ...

Portraying double Higgs at the Large Hadron Collider II

Journal of High Energy Physics, 2022
The Higgs potential is vital to understand the electroweak symmetry breaking mechanism, and probing the Higgs self-interaction is arguably one of the most important physics targets at current and upcoming collider experiments.

Anomalous couplings in single Higgs production through γγ collisions [PDF]

Zeitschrift f�r Physik C Particles and Fields, 1995
We show that single Higgs production in $ $ collisions through laser backscattering provides the best way to look for New Physics (NP) effects inducing anomalous Higgs couplings. Our analysis is based on the four $dim=6$ operators $ _{UB}$, $ _{UW}$, $\ol _{UB}$ and $\ol _{UW}$ which describe New Physics effects in this sector.

SMEFTs living on the edge: determining the UV theories from positivity and extremality

Journal of High Energy Physics, 2022
We study the “inverse problem” in the context of the Standard Model Effective Field Theory (SMEFT): how and to what extend can one reconstruct the UV theory, given the measured values of the operator coefficients in the IR?

Probing non-standard HVV (V = W, Z) couplings in single Higgs production at future electron-proton collider

Journal of High Energy Physics, 2022
The couplings of the Higgs boson (H) with massive gauge bosons of weak interaction (V = W, Z), can be probed in single Higgs boson production at the proposed future Large Hadron-Electron Collider (LHeC).
