Flavor in SU(5)$SU(5)$ Finite Grand Unified Models

open access: yesFortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...

Interpreting light scalar excesses and heavy scalar cascades in the μ-term extended NMSSM

open access: yesJournal of High Energy Physics
The hints for a scalar resonance near 95 GeV in the LEP b b ¯ $$ b\overline{b} $$ channel and in the LHC diphoton searches remain among the most persistent small deviations in the Higgs sector.

On Calabi‐Yau Manifolds at Strong Topological String Coupling

open access: yesFortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract It was recently shown that integrating out M2 states on Calabi‐Yau manifolds captures non‐perturbative topological string physics in the free energy. In this note, It has been shown that the resulting expression manifests a certain duality symmetry: the free energy at strong string coupling is equal to the Calabi‐Yau period at weak string ...

Linearizing extended nonlinear supersymmetry in two dimensional spacetime

open access: yesNuclear Physics B, 2019
We linearize nonlinear supersymmetry in the Volkov–Akulov (VA) theory for extended SUSY in two dimensional spacetime (d=2) based on the commutator algebra.

Moduli anomalies and local terms in the operator product expansion

open access: yesJournal of High Energy Physics, 2018
Local terms in the Operator Product Expansion in Superconformal Theories with extended supersymmetry are identified. Assuming a factorized structure for these terms their contributions are discussed.

The dark side of double-tensor multiplets

open access: yesJournal of High Energy Physics
We explore the properties of a set of free double-tensor multiplets in N $$ \mathcal{N} $$ = 2 supersymmetry, focusing on their behavior within rigid superspace.

Supergravity and local extended supersymmetry

open access: yesPhysics Letters B, 1977
Abstract We consider the possibility of having supergravity theories with several (N > 2) Majorana spin 3 2 gauge fields. From the spinor dual model one can infer the existence of these theories with (Yang-Mills) matter coupling up to N = 4 spin 3 2 gauge fields. In the present note we construct the simplest of these theories, i.e. pure

The anti-de Sitter supergeometry revisited

open access: yesJournal of High Energy Physics
In a supergravity framework, the N $$ \mathcal{N} $$ -extended anti-de Sitter (AdS) superspace in four spacetime dimensions, AdS 4 4 N $$ {\textrm{AdS}}^{4\left|4\mathcal{N}\right.} $$ , is a maximally symmetric background that is described by a curved ...
