Non-standard soft supersymmetry breaking
نویسندگان
چکیده
We explore a more general class of soft supersymmetry-breaking masses and interactions than that usually considered, both in general and in the MSSM context, where our results for the one-loop β-functions correct some errors in the literature. We identify a new class of one-loop finite supersymmetric theories.

TASI 2008 Lectures: Introduction to Supersymmetry and Supersymmetry Breaking
These lectures, presented at TASI 08 school, provide an introduction to supersymmetry and supersymmetry breaking. We present basic formalism of supersymmetry, supersymmetric non-renormalization theorems, and summarize non-perturbative dynamics of supersymmetric QCD.We then turn to discussion of tree level, non-perturbative, and metastable supersymmetry breaking. We introduce Minimal Supersymmet...
متن کاملSoft Supersymmetry Breaking Induced by Higher-derivative Supergravitation in the Electroweak Standard Model
Abstract. 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. The general structure of the soft supersymmetry breaking terms is presented and a new scenario for understanding the gauge hierarchy problem, based on the funct...

The renormalization of the Minimal Supersymmetric Standard Model is discussed. In particular we focus on the soft-supersymmetry breaking sector of the MSSM and comment on non-renormalization theorems.

متن کاملSupersymmetry Phenomenology (with a Broad Brush)
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. The rest of the lectures are devoted to understanding supersymmetry breaking more m...
متن کاملSupersymmetric Partners of Oblique Corrections
We discuss the violation of the equality of the gauge coupling and gaugino coupling in the presence of soft supersymmetry breaking. Although this is a hard supersymmetry breaking effect, there are finite contributions to this difference which can be determined as a function of the soft supersymmetry breaking masses. The largest sources of this difference are the “superoblique” corrections, whic...
