Electroweak baryogenesis and electron EDM in the TNMSSM

European Physical Journal C: Particles and Fields
We have studied the impact of CP-violating (CPV) effects on electroweak baryogenesis (EWBG) and the electric dipole moment (EDM) of electron ( $$d_e$$ d e ), the electric dipole moment (EDM) of mercury neutron ( $$d_n$$ d n ) and the electric dipole ...

Celestial Topology, Symmetry Theories, and Evidence for a NonSUSY D3‐Brane CFT

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract Symmetry Theories (SymThs) provide a flexible framework for analyzing the global categorical symmetries of a D$D$‐dimensional QFTD$\text{QFT}_{D}$ in terms of a (D+1)$(D+1)$‐dimensional bulk system SymThD+1$\text{SymTh}_{D+1}$. In QFTs realized via local string backgrounds, these SymThs naturally arise from dimensional reduction of the linking

Fast and interpretable support vector classification based on the truncated ANOVA decomposition

GAMM-Mitteilungen, Volume 48, Issue 1, March 2025.
Abstract Support vector machines (SVMs) are an important tool for performing classification on scattered data, where one usually has to deal with many data points in high‐dimensional spaces. We propose solving SVMs in primal form using feature maps based on trigonometric functions or wavelets.

Exploring sensitivity to NMSSM signatures with low missing transverse energy at the LHC

Journal of High Energy Physics, 2018
We examine scenarios in the Next-to-Minimal Supersymmetric Standard Model (NMSSM), where pair-produced squarks and gluinos decay via two cascades, each ending in a stable neutralino as Lightest Supersymmetric Particle (LSP) and a Standard Model (SM)-like

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.

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.

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.

Light and compressed gluinos at the LHC via string theory

European Physical Journal C: Particles and Fields, 2017
In this article, we show that making global fits of string theory model parameters to data is an interesting mechanism for probing, mapping and forecasting connections of the theory to real world physics.

Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry, and Complex Multiplication

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

Searches for direct supersymmetric gaugino and slepton pair production in final states with leptons with the ATLAS detector

EPJ Web of Conferences, 2013
A search for direct production of supersymmetric gauginos and sleptons in final states with two and three leptons is presented. The two lepton analysis uses 4.7 fb−1 of proton-proton collision data at √s = 7 TeV, while the three lepton analysis uses 13 ...
