Superspace higher derivative terms in two dimensions
Journal 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.

Lattice study of supersymmetry breaking in N=2 supersymmetric quantum mechanics
Nuclear Physics B, 2019 We study supersymmetry breaking from a lattice model of N=2 supersymmetric quantum mechanics using a direct computational method proposed in arXiv:1803.07960. The vanishing Witten index is realized as a numerical result in high precision. The expectation

Partial breaking of supersymmetry, open strings and M-theory [PDF]
, 1998 We study total and partial supersymmetry breaking by freely acting orbifolds, or equivalently by Scherk-Schwarz compactifications, in type I string theory.

N=2→0 super no-scale models and moduli quantum stability
Nuclear Physics B, 2017 We consider a class of heterotic N=2→0 super no-scale Z2-orbifold models. An appropriate stringy Scherk–Schwarz supersymmetry breaking induces tree level masses to all massless bosons of the twisted hypermultiplets and therefore stabilizes all twisted ...

Sparticle spectrum and constraints in anomaly mediated supersymmetry breaking models [PDF]
, 2002 We study in detail the particle spectrum in anomaly mediated supersymmetry breaking models in which supersymmetry breaking terms are induced by the super-Weyl anomaly.

Axion-like particles from soft supersymmetry breaking
Journal of High Energy PhysicsWe study a supersymmetric effective field theory in which the mass of an axion-like particle (ALP) is generated predominantly by soft supersymmetry-breaking effects.

Supersymmetry breaking from superstrings [PDF]
, 1990 The gauge hierarchy problem is briefly reviewed and a class of effective field theories obtained from superstrings is described. These are characterized by a classical symmetry, related to the space-time duality of string theory, that is responsible for ...

Soft supersymmetry breaking terms from supergravity and superstring models [PDF]
, 1997 We review the origin of soft supersymmetry-breaking terms in N=1 supergravity models of particle physics. We first consider general formulae for those terms in general models with a hidden sector breaking supersymmetry at an intermediate scale.

Semiclassical monopole calculations in supersymmetric gauge theories [PDF]
, 2000 We investigate semiclassical contributions to correlation functions in N = 1 supersymmetric gauge theories. Our principal example is the gluino condensate, which signals the breaking of chiral symmetry, and should be exactly calculable, according to a ...
