Unified models of the QCD axion and supersymmetry breaking
Nuclear Physics B, 2017 Similarities between the gauge meditation of supersymmetry breaking and the QCD axion model suggest that they originate from the same dynamics. We present a class of models where supersymmetry and the Peccei–Quinn symmetry are simultaneously broken.

Spontaneous supersymmetry breaking in the 2D N=1 Wess-Zumino model. [PDF]
Physical Review Letters, 2013 We study the phase diagram of the two-dimensional N=1 Wess-Zumino model on the lattice using Wilson fermions and the fermion loop formulation. We give a complete nonperturbative determination of the ground state structure in the continuum and infinite ...

New Models of Gauge and Gravity Mediated Supersymmetry Breaking [PDF]
Phys.Rev.D55:5508-5519,1997, 1996 We show that supersymmetry breaking in a class of theories with SU(N) x SU(N-2) gauge symmetry can be studied in a calculable sigma model. We use the sigma model to show that the supersymmetry breaking vacuum in these theories leaves a large subgroup of flavor symmetries intact, and to calculate the masses of the low-lying states.

Dynamical Supersymmetry Breaking [PDF]
Modern Physics Letters A, 1997 We review mechanisms of dynamical supersymmetry breaking. Several observations that narrow the search for possible models of dynamical supersymmetry breaking are summarized. These observations include the necessary and sufficient conditions for supersymmetry breaking.

Branes and dynamical supersymmetry breaking [PDF]
Nuclear Physics B, 1998 We study dynamical supersymmetry breaking in four dimensions using the fivebrane of M theory, in particular for the Izawa-Yanagida-Intriligator-Thomas (IYIT) model, which we realize as the worldvolume theory of a certain M-theory fivebrane configuration.

Scale Hierarchies in Particle Physics and Cosmology
EPJ Web of Conferences, 2016 We discuss possible connections between several scales in particle physics andcosmology, such the the electroweak, inflation, dark energy and Planck scales.

Spontaneous breaking of supersymmetry [PDF]
, 2008 There has been recently a revival of interest in supersymmetric gauge theories, stimulated by the hope that supersymmetry might help in clarifying some of the questions which remain unanswered in the so called Grand Unified Theories and in particular the gauge hierarchy problem.

D -term triggered dynamical supersymmetry breaking [PDF]
, 2013 We present the mechanism of the dynamical supersymmetry breaking at the metastable vacuum recently uncovered in the $\mathcal{N}=1$ $U(N)$ supersymmetric gauge theory that contains adjoint superfields and that is specified by K\"ahler and noncanonical ...

Dark Dimension With (Little) Strings Attached
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron
