Operator analysis for precision electroweak physics

Physics Letters B, 1991
The impact of new physics associated with the Higgs sector on precision electroweak physics is examined. We assume that at low energies the degrees of freedom are those of the standard model with minimal particle content (i.e., three generations of quarks and leptons and one Higgs doublet), and that the new physics is very weakly coupled to the quarks ...

Precision Electroweak Tests of the Standard Model

Physics Reports, 2004
The study of electron-positron collisions at LEP, together with additional measurements from other experiments, in particular those at SLC and at the Tevatron, has allowed for tests of the electroweak Standard Model with unprecedented accuracy. We review

The importance of flavor in SMEFT Electroweak Precision Fits

Journal of High Energy Physics, 2023
Effective field theory tools are essential for exploring non-Standard Model physics at the LHC in the absence of the discovery of new light particles.

A Proposal for a Low‐Frequency Axion Search in the 1–2 μ$\umu$ eV Range and Below with the BabyIAXO Magnet

Annalen der Physik, Volume 535, Issue 12, December 2023., 2023
This article describes the implementation of low‐frequency axion haloscope setups inside the future BabyIAXO magnet. The RADES proposal has a potential sensitivity to the axion‐photon coupling down to values corresponding to the KSVZ model, in the mass range between 1 and 2 μ$\umu$eV.

Resurgence of a de Sitter Glauber‐Sudarshan State: Nodal Diagrams and Borel Resummation

Fortschritte der Physik, Volume 71, Issue 12, December 2023., 2023
Abstract It is shown in this article that an explicit construction of a four‐dimensional de Sitter space may be performed using a diagrammatic approach via nodal diagrams emanating from the path integral representation of the Glauber‐Sudarshan state. Sum of these diagrams typically leads to an asymptotic series of Gevrey kind which can then be Borel ...

The Low‐Scale Seesaw Solution to the MW$M_W$ and (g−2)μ$(g-2)_\umu$ Anomalies

Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023
Abstract The recent CDF‐II measurement of the W‐boson mass shows a strong tension with the corresponding Standard Model prediction. Once active neutrino masses are explained in the context of the Low‐Scale Seesaw mechanisms, this tension can be resolved.

Lepton-nucleon interactions at the next-to-the-leading order [PDF]

, 2009
Next-to-Leading-Order (NLO) effects play a crucial role in tests of the Standard Model (SM), and require careful theoretical evaluation. Electroweak physics, which has just entered the precision age, is an excellent place to search for new physics, but ...

Probing HNL‐ALP Couplings at Colliders

Fortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023
Abstract Axion‐like particles (ALPs) and heavy neutral leptons (HNLs) are both well‐motivated extensions of the Standard Model. As ALPs couple to on‐shell fermions proportionally to their masses, processes involving both types of particles may give rise, for TeV HNLs, to relevant phenomenology at colliders.

Honeycomb‐Layered Oxides With Silver Atom Bilayers and Emergence of Non‐Abelian SU(2) Interactions

Advanced Science, Volume 10, Issue 6, February 24, 2023., 2023
This work reports a new class of honeycomb‐layered oxides (Ag2 M 2TeO6 (M is a transition or alkaline‐earth metal)) comprising unconventional sub‐valent bilayered silver‐rich domains (Ag6 M 2TeO6), as elucidated via aberration‐corrected transmission electron microscopy.
