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

From linear to non-linear SUSY and back again
Journal of High Energy Physics, 2017 We show that couplings of the goldstino field, appearing when global supersymmetry is broken, can always be described in superspace by means of a nilpotent chiral superfield X, satisfying X 2 = 0.

The effective lagrangian of supersymmetric Yang-Mills theory [PDF]
Physics Letters B, 1986 Abstract The one-loop effective action of the supersymmetric Yang-Mills theory in the presence of a covariantly constant Yang-Mills superfield is calculated. This is done with the help of Schwinger's proper time method. The propagator of the Yang-Mills superfield in the presence of a non-vanishing background superfield is derived in a closed form ...

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.

Ghostbusters in f (R) supergravity
Journal of High Energy Physics, 2018 f (R) supergravity is known to contain a ghost mode associated with higher-derivative terms if it contains R n with n greater than two. We remove the ghost in f (R) supergravity by introducing auxiliary gauge field to absorb the ghost. We dub this method

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.

Effective potentials for a class of supersymmetric theories
Physics Letters B, 1982 Abstract We compute one- and two-loop corrections to the effective potential for a class of models in which supersymmetry is spontaneously broken in an O'Raifeartaigh model.

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.

Non-factorizable superamplitudes for massive N $$ \mathcal{N} $$ = 1 superstates
Journal of High Energy PhysicsIn this paper we study non-factorizable N $$ \mathcal{N} $$ = 1 superamplitudes for massive chiral superstates. We demonstrate how little group scaling and the supersymmetric Ward identities determine the form of non-factorizable massless superamplitudes,
