Remodeling the Pentagon After the Events of 2/23/06
T. Banks

TL;DR
This paper simplifies the Pentagon model of TeV scale physics using a meta-stable SUSY breaking mechanism, leading to a model with distinctive signatures, a new strongly interacting sector, and a viable dark matter candidate.
Contribution
It introduces a simplified Pentagon model with a single scalar field and no low energy axion, incorporating a new strongly interacting sector and addressing flavor and CP violation issues.
Findings
Identifies a new strongly interacting sector at ~1.5 TeV
Proposes a dark matter candidate as a pseudo-Goldstone boson
Predicts distinctive collider signatures such as $l^+ l^- X$ plus missing energy
Abstract
The meta-stable SUSY breaking mechanism of Intriligator Seiberg and Shih can be used to simplify the Pentagon model of TeV scale physics. The simplified model has only a single scalar field and no troublesome low energy axion. One significant signature is plus missing energy, where might be the two photons of gauge mediated models, but is likely to be different. There is a new strongly interacting sector with a scale around 1.5 TeV. The penta-hadrons of this sector have masses of order 6 TeV or more. Dark matter is probably the pseudo-goldstone boson of spontaneously broken penta-baryon number. This can be a viable dark matter candidate if an appropriate asymmetry in penta-baryon number is generated in the early universe. The pseudo-Goldstone particle has a mass of eV and is produced predominantly in flavor changing charged current decays of ordinary particles.…
