$W$-Boson Mass, Electroweak Precision Tests and SMEFT [PDF]
, 2022 Recently the CDF collaboration at the Tevatron reported a significant discrepancy between the direct measurement of the $W$-boson mass and its Standard Model (SM) prediction based on electroweak precision tests (EWPTs).

A sensitivity study of VBS and diboson WW to dimension-6 EFT operators at the LHC
Journal of High Energy Physics, 2022 We present a parton-level study of electro-weak production of vector-boson pairs at the Large Hadron Collider, establishing the sensitivity to a set of dimension-six operators in the Standard Model Effective Field Theory (SMEFT).

Probing top-quark operators with precision electroweak measurements [PDF]
Chinese Physics C, High Energy Physics & Nuclear Physics, 2022 In the standard model effective field theory, operators involving the top quark are generally difficult to probe and can generate sizable loop contributions to electroweak precision observables measured by past and future lepton colliders. Could the high

MUonE, muon $g-2$ and electroweak precision constraints within 2HDMs [PDF]
, 2022 Two Higgs doublet models are attractive scenarios for physics beyond the Standard Model. In particular, lepton-specific manifestations remain contenders to explain the observed discrepancy between the anomalous magnetic moment of the muon a µ predicted ...

Supersymmetric explanation of the muon g – 2 anomaly with and without stable neutralino
Journal of High Energy Physics, 2022 In this paper we explore the possibility of explaining the muon g − 2 anomaly in various types of supersymmetric extensions of the Standard Model.

Precision electroweak measurements at the LHeC and the FCC-eh [PDF]
Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2021), 2022 The proposed electron-proton collider experiments LHeC and FCC-eh at CERN are the highest resolution microscopes that can be realised in the present century and they would represent a really unique research facility.

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 ...
