Electroweak symmetry breaking from supersymmetry breaking with a bosonic seesaw mechanism [PDF]
Physical Review D, 2005 We introduce the idea of bosonic seesaw mechanism in analogy with the seesaw mechanism. Bosonic seesaw is a new symmetry breaking mechanism, and we apply it to explain electroweak symmetry breaking as an inevitable consequence of supersymmetry breaking. The breaking of electroweak symmetry occurs at tree level once supersymmetry is broken.

R-symmetry and supersymmetry breaking in 3DWZ models [PDF]
Journal of High Energy Physics, 2009 We analyze metastable supersymmetry breaking in 3D WZ models. We study the regime of validity of the perturbative computation for superpotentials with marginal and relevant couplings. Lifetime of the metastable states in presence of a triangular potential barrier is estimated.

Supersymmetry breaking, R-symmetry, and conformal dynamics [PDF]
, 2009 We study N=1 global and local supersymmetric theories with a continuous global U(1)_R symmetry. We discuss conditions for supersymmetry (SUSY) breaking and vacuum structures of R-symmetric SUSY models. Especially we find the conditions for R-symmetry breaking and runway vacua in global supersymmetric theories.

Supersymmetry breaking, R-symmetry breaking and metastable vacua [PDF]
Journal of High Energy Physics, 2007 Models of spontaneous supersymmetry breaking generically have an R-symmetry, which is problematic for obtaining gaugino masses and avoiding light R-axions. The situation is improved in models of metastable supersymmetry breaking, which generically have only an approximate R-symmetry.

Soft supersymmetry breaking terms fromA4lepton flavor symmetry [PDF]
Journal of High Energy Physics, 2008 We study the supersymmetric model with the A4 lepton flavor symmetry, in particular soft supersymmetry breaking terms, which are predicted from the A4 lepton flavor symmetry. We evaluate soft slepton masses and A-terms within the framework of supergravity theory. Constraints due to experiments of flavor changing neutral current processes are examined.

Gaugino Masses from Misaligned Supersymmetry Breaking and R-Symmetry Breaking Spurions
Symmetry, 2023 In gauge mediation models with multiple spurion fields breaking SUSY and the R-symmetry separately, we show that it is possible to generate gaugino masses in one loop if the R-charge arrangement satisfies a certain condition. The resulting gaugino masses are calculated and suppressed by a power of the messenger’s mass scale.

A Note on Modular Invariant Species Scale and Potentials
Fortschritte der Physik, Volume 71, Issue 10-11, November 2023., 2023 Abstract The species scale provides an upper bound for the ultraviolet cutoff of effective theories of gravity coupled to a number of light particle species. Modular invariant (super‐)potentials provide a simple and computable expression of the species scale as a function of the moduli in toroidal orbifold compactifications of type II and heterotic ...

Supersymmetric Reshaping and Higher‐Dimensional Rearrangement of Photonic Lattices
Laser &Photonics Reviews, Volume 17, Issue 10, October 2023., 2023 Self‐imaging Jx photonic lattices enable perfect transfer of quantum and classical states, yet are challenging to implement at scale. In this paper, supersymmetry is harnessed to construct 2D systems with spectra identical to that of 1D Jx lattices that retain their key imaging and state transfer properties, while requiring dramatically fewer distinct ...
