Superspace higher derivative terms in two dimensions

open access: yesJournal of High Energy Physics, 2017
We study (2, 2) and (4, 4) supersymmetric theories with superspace higher derivatives in two dimensions. A characteristic feature of these models is that they have several different vacua, some of which break supersymmetry.

Superstring cosmology for N_4 = 1 -> 0 superstring vacua

open access: yes, 2010
We study the cosmology of perturbative heterotic superstring theory during the radiation-like era for semi-realistic backgrounds with initial $\N=1$ supersymmetry.

What is the scale of supersymmetry breaking? [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1997
For a long time, it has been widely assumed that if the underlying laws of nature are supersymmetric, supersymmetry is broken at a scale intermediate between the weak scale and the Planck mass. The construction of realistic models of dynamical supersymmetry breaking in which supersymmetry is broken at a much lower scale, as well as a growing ...

Metastable supersymmetry breaking in terms of Peccei–Quinn mechanism

open access: yesPhysics Letters B, 2018
Gauge-mediated supersymmetry breaking at metastable vacuum is reconsidered in terms of the Peccei–Quinn (PQ) mechanism. We suggest that for acceptable μ-value generation, such a class of model should involve messenger mass generation via the PQ-breaking ...

A functional perspective on emergent supersymmetry

open access: yesJournal of High Energy Physics, 2017
We investigate the emergence of N $$ \mathcal{N} $$ = 1 supersymmetry in the long-range behavior of three-dimensional parity-symmetric Yukawa systems. We discuss a renormalization approach that manifestly preserves supersymmetry whenever such symmetry is

A unified approach to supersymmetry breaking [PDF]

open access: yesPhysics Letters B, 2012
General formulae for the soft SUSY breaking terms, valid in any SUGRA context, were derived in the mid-nineties. Since SUSY is not expected to have quantum anomalies, they should be valid in the quantum theory and be RG invariant down to the soft SUSY breaking scale. This observation enables us to give a uniform treatment of all phenomenological models
