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

On Calabi‐Yau Manifolds at Strong Topological String Coupling
Fortschritte 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 ...

All partial breakings in N=2 $$ \mathcal{N}=2 $$ supergravity with a single hypermultiplet
Journal of High Energy Physics, 2018 We consider partial supersymmetry breaking in N=2 $$ \mathcal{N}=2 $$ supergravity coupled to a single vector and a single hypermultiplet. This breaking pattern is in principle possible if the quaternion-Kähler space of the hypermultiplet admits (at ...

Extended supersymmetry and super-BF gauge theories [PDF]
Nuclear Physics B, 1994 The absence of fermion kinetic terms in supersymmetric-BF gauge theories is established. We do this by means of explicit off-shell (superspace) constructions. As part of our study we give the superspace constraints for D=3, N=4 super Yang-Mills along with the D=3, N=4 superconformal algebra.

IET Image Processing, Volume 18, Issue 14, Page 4760-4777, 11 December 2024.The proposed method enables the consideration of more complex affinity relationship beyond pairwise while keeping computational demands within a manageable threshold. A factorization for global affinity matrix of any k graphs is proposed. The proposed method unifies existing multi‐graph matching methods and opens new avenues for future studies ...

Supergravity and local extended supersymmetry
Physics 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

Focus point supersymmetry in extended gauge mediation [PDF]
Journal of High Energy Physics, 2014 We propose a small extenion of the minimal gauge mediation through the combination of extended gauge mediation and conformal sequestering. We show that the focus point supersymmetry can be realized naturally, and the fine-tuning is signifcantly reduced compared to the minimal gauge mediation and extended gauge mediation without focus point.

Asymptotic Behavior of Saxion–Axion System in Stringy Quintessence Model
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract The late time behavior of the slow‐roll parameter in the stringy quintessence model is studied when axion as well as saxion are allowed to move. Even though the potential is independent of the axion at tree level, the axion can move through its coupling to the saxion and the background geometry.

Predicting Alignment in a Two Higgs Doublet Model
Proceedings, 2019 We show that a non-abelian global S U ( 2 ) R R-symmetry acting on the quartic part of the two Higgs Doublet Model leads, at tree-level, to an automatic alignment without decoupling.

de Sitter State in Heterotic String Theory
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.
