Charged Current Universality in the Minimal Supersymmetric Standard Model [PDF]

Physical Review Letters, 2002
We compute the complete one-loop contributions to low-energy charged current weak interaction observables in the minimal supersymmetric standard model (MSSM). We obtain the constraints on the MSSM parameter space which arise when precision low-energy charged current data are analyzed in tandem with measurements of the muon anomaly. While the data allow

Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Electroweak precision observables in the minimal supersymmetric standard model [PDF]

Physics Reports, 2006
The current status of electroweak precision observables in the Minimal Supersymmetric Standard Model (MSSM) is reviewed. We focus in particular on the $W$ boson mass, M_W, the effective leptonic weak mixing angle, sin^2 theta_eff, the anomalous magnetic moment of the muon, (g-2)_ , and the lightest CP-even MSSM Higgs boson mass, m_h.

Double Copy From Tensor Products of Metric BV■‐Algebras

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.

Light Charged Higgs Boson and Supersymmetry

, 2001
A possible discovery of a relatively light charged Higgs boson H^+ in near future experiments, with a mass M_{H+} ~< 110 GeV, together with the present LEP2 direct limits on the chargino and neutral Higgs sectors, would disfavour the minimal ...

The Minimal Supersymmetric Fat Higgs Model [PDF]

, 2003
We present a calculable supersymmetric theory of a composite ``fat'' Higgs boson. Electroweak symmetry is broken dynamically through a new gauge interaction that becomes strong at an intermediate scale. The Higgs mass can easily be 200-450 GeV along with

A functional treatment of small instanton-induced axion potentials

Journal of High Energy Physics
We present a functional method to perform complete one-instanton calculations of the axion potential. This is done for an SU(N) gauge theory with a matter content in any representation of the gauge group.

Next-to-Minimal Supersymmetric Standard Model with the Gauge Mediation of Supersymmetry Breaking [PDF]

, 1997
We study the next-to-minimal supersymmetric standard model (NMSSM) as the simplest candidate solution to the {mu}-problem in the context of the gauge mediation of supersymmetry breaking (GMSB).

Geometric Relational Framework for General‐Relativistic Gauge Field Theories

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract It is recalled how relationality arises as the core insight of general‐relativistic gauge field theories from the articulation of the generalized hole and point‐coincidence arguments. Hence, a compelling case for a manifestly relational framework ensues naturally.
