Exploring charge and color breaking vacuum in non-holomorphic MSSM
Journal of High Energy Physics, 2017 Non-Holomorphic MSSM (NHSSM) shows various promising features that are not easily obtained in MSSM. However, the additional Non-Holomorphic (NH) trilinear interactions that attribute to the interesting phenomenological features, also modify the effective

Resonant slepton production and right sneutrino dark matter in left-right supersymmetry
Journal of High Energy Physics, 2017 Right-handed sneutrinos are natural components of left-right symmetric supersymmetric models where the gauge sector is extended to include right-handed weak interactions.

Gravitational waves from first-order electroweak phase transition in a model with light sgoldstinos
Journal of High Energy Physics, 2022 We study previously unexplored possibility of triggering the first order electroweak phase transition (EWPT) by interactions of the Standard Model (SM) particles with the sector responsible for low scale supersymmetry breaking.

The light sgoldstino phenomenology: explanations for the muon (g − 2) deviation and KOTO anomaly
Journal of High Energy Physics, 2020 In this work, we study the long-standing experimental anomaly in muon (g −2) and also recent anomalous excess in K L → π 0 + v v ¯ $$ {K}_L\to {\pi}^0+v\overline{v} $$ at the J-PARC KOTO experiment with sgoldstino.

Foundations of Ghost Stability
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

Singlino-dominated dark matter in general NMSSM
Journal of High Energy Physics, 2021 The general Next-to-Minimal Supersymmetric Standard Model (NMSSM) describes the singlino-dominated dark-matter (DM) property by four independent parameters: singlet-doublet Higgs coupling coefficient λ, Higgsino mass μ tot, DM mass m χ ˜ 1 0 $$ {m}_ ...

Sweet Spot Supersymmetry and Composite Messengers [PDF]
Phys.Lett.B663:242-246,2008, 2007 Sweet spot supersymmetry is a phenomenologically and cosmologically perfect framework to realize a supersymmetric world at short distance. We discuss a class of dynamical models of supersymmetry breaking and its mediation whose low-energy effective description falls into this framework.

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.

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 ...
