Note on moduli stabilization, supersymmetry breaking, and axiverse [PDF]
, 2011 We study properties of moduli stabilization in the four dimensional $\mathcal{N}=1$ supergravity theory with heavy moduli and would-be saxion-axion multiplets, including light string-theoretic axions.

Radiative Scherk-Schwarz supersymmetry breaking [PDF]
, 2002 We analyze the Scherk-Schwarz (SS) supersymmetry breaking in brane-world five dimensional theories compactified on the orbifold $S^1/\mathbb{Z}_2$. The SS breaking parameter is undetermined at the tree-level (no-scale supergravity) and can be interpreted

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.

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.

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 ...

, 1996 We show how spontaneous supersymmetry breaking in the vacuum state of higher-derivative supergravity is transmitted, as explicit soft supersymmetry-breaking terms, to the effective Lagrangian of the standard electroweak model.

Proton decay, supersymmetry breaking and its mediation [PDF]
, 2006 We study the breaking of supersymmetry and its transmission to the light states in the context of the minimal SU(5) grand unified theory, with no additional singlets. This simple theory can be taken as a prototype for a program of breaking simultaneously

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.
