Heavy Thresholds, Slepton Masses and the $\mu$ Term in Anomaly Mediated Supersymmetry Breaking [PDF]
, 1999 The effects of heavy mass thresholds on anomaly-mediated soft supersymmetry breaking terms are discussed. While heavy thresholds completely decouple to lowest order in the supersymmetry breaking, it is argued that they do affect the breaking terms at ...

New supersymmetry algebras from partial supersymmetry breaking [PDF]
arXiv, 1998 In this talk we will study the partial breaking of supersymmetry in flat and anti de Sitter space. We will see that partial breaking in flat space can be accomplished using either of two representations for the massive N=1 spin-3/2 multiplet. We will "unHiggs" each representation and find a new N=2 supergravity and a new N=2 supersymmetry algebra.

Hierarchical Supersymmetry Breaking in Superstring Derived Standard--like Models [PDF]
, 1994 We examine the problem of supersymmetry breaking in realistic superstring standard--like models which are constructed in the free fermionic formulation.

2004 TASI Lectures on Supersymmetry Breaking [PDF]
arXiv, 2005 These lectures give an introduction to the problem of finding a realistic and natural extension of the standard model based on spontaneously broken supersymmetry. Topics discussed at some length include the effective field theory paradigm, coupling constants as superfield spurions, gauge mediated supersymmetry breaking, and anomaly mediated ...

Supersymmetry Breaking Vacua from M Theory Fivebranes
, 2007 We consider intersecting brane configurations realizing N=2 supersymmetric gauge theories broken to N=1 by multitrace superpotentials, and softly to N=0.

Interpolation of partial and full supersymmetry breakings in N=2 supergravity
Nuclear Physics B, 2019 We discuss an N=2 supergravity model that interpolates the full and the partial supersymmetry breakings. In particular, we find the conditions for an N=0 Minkowski vacuum, which is continuously connected to the partial-breaking (N=1 preserving) one.

Supersymmetry breaking warped throats and the weak gravity conjecture
Journal of High Energy Physics, 2019 We generalize the swampland criterion forbidding stable non-supersymmetric AdS vacua and propose a new swampland conjecture forbidding stable non-supersymmetric “locally AdS” warped throats.

Scanning of the Supersymmetry Breaking Scale and the Gravitino Mass in Supergravity
, 2016 We consider the minimal three-form ${\cal N}=1$ supergravity coupled to nilpotent three-form chiral superfields. The supersymmetry breaking is sourced by the three-forms of the chiral multiplets, while the value of the gravitino mass is controlled by the

Supersymmetry Phenomenology With a Broad Brush [PDF]
arXiv, 1996 These lectures provide an introduction to supersymmetry phenomenology. They include an overview of the Minimal Supersymmetric Standard Model. The notion of soft breaking is explained, constraints on the standard soft breaking parameters are reviewed, and the standard ansatz of universal soft masses is discussed.

Hybrid inflation from supersymmetry breaking
European Physical Journal C: Particles and FieldsWe extend a recently proposed framework, dubbed inflation by supersymmetry breaking, to hybrid inflation by introducing a waterfall field that allows to decouple the supersymmetry breaking scale in the observable sector from the inflation scale, while ...
