Explaining electron and muon g − 2 anomaly in SUSY without lepton-flavor mixings
Journal of High Energy Physics, 2019 We propose a SUSY scenario to explain the current electron and muon g − 2 discrepancies without introducing lepton flavor mixings. Threshold corrections to the Yukawa couplings can enhance the electron g − 2 and flip the sign of the SUSY contributions ...

Proton decay: flipped vs. unflipped SU(5)
Journal of High Energy Physics, 2020 We analyze nucleon decay modes in a no-scale supersymmetric flipped SU(5) GUT model, and contrast them with the predictions for proton decays via dimension-6 operators in a standard unflipped supersymmetric SU(5) GUT model.

Multilepton signals of heavier electroweakinos at the LHC
Journal of High Energy Physics, 2017 As a sequel to our recent paper we examine the phenomenology of the full electroweakino sector of the pMSSM without invoking the ad hoc but often employed assumption that the heavier ones are decoupled.

UV Shadows in EFTs: Accidental Symmetries, Robustness and No‐Scale Supergravity
Fortschritte der Physik, Volume 68, Issue 10, October 2020., 2020 Abstract We argue that accidental approximate scaling symmetries are robust predictions of weakly coupled string vacua, and show that their interplay with supersymmetry and other (generalised) internal symmetries underlies the ubiquitous appearance of no‐scale supergravities in low‐energy 4D EFTs.

Tagging new physics with charm
Journal of High Energy Physics, 2017 We propose a new variable, the charm fraction, for collider searches for new physics. We analyze this variable in the context of searches for simplified supersymmetry models with squarks, the gluino, and the bino, assuming that only the lightest ...

TASI 2008 Lectures: Introduction to Supersymmetry and Supersymmetry Breaking [PDF]
, 2009 These lectures, presented at TASI 08 school, provide an introduction to supersymmetry and supersymmetry breaking. We present basic formalism of supersymmetry, supersymmetric non-renormalization theorems, and summarize non-perturbative dynamics of supersymmetric QCD.

Supersymmetry Breaking at Low Energies [PDF]
Nucl.Phys.Proc.Suppl.192-193:40-60,2009, 2009 These lectures, given at the Cargese Summer school in 2008, provide an introduction to dynamical supersymmetry breaking and gauge mediation, with emphasis on the recent appreciation of the possible role of metastable supersymmetry breaking, and the evolving understanding of General Gauge Mediation.

Probing SUSY effects in K S 0 → μ + μ −
Journal of High Energy Physics, 2018 We explore supersymmetric contributions to the decay K S 0 → μ + μ −, in light of current experimental data. The Standard Model (SM) predicts ℬKS0→μ+μ−≈5×10−12 $$ \mathrm{\mathcal{B}}\left({K}_S^0\to {\mu}^{+}{\mu}^{-}\right)\approx 5\times {10}^{-12} $$.

Electroweak signatures of gauge-mediated supersymmetry breaking in multiple hidden sectors
Journal of High Energy Physics, 2022 This paper discusses electroweak collider signatures of the NMSSM with multiple-sector gauge mediation. We focus on the production of neutralinos and charginos which cascade decay into standard model particles and lighter supersymmetric particles, with ...

Effective Messenger Sector from Dynamical Supersymmetry Breaking [PDF]
Nucl.Phys. B497 (1997) 31-40, 1996 In the framework of the dynamical supersymmetry breaking we construct the messenger sector as the effective theory of supersymmetry breaking sector, which is based on SU(3) \times SU(2) model of Affleck, Dine and Seiberg. In our model, messenger superfields with non-renormalizable interaction are contained.
