Gauge Mediated Supersymmetry Breaking and Multi-TeV Gamma-Rays from the Galactic Center

ArXiv hep-ph/0412048 (2004)

Authors:

Dan Hooper, John March-Russell

Abstract:

Recently, the HESS telescope has observed a gamma-ray spectrum from the galactic center extending to at least $\sim$10 TeV. Although it has been suggested that this could be the product of annihilating dark matter particles, the candidates most frequently discussed (such as neutralinos) are far too light to account for this flux. In this letter, we consider stable particles from the messenger sector of gauge mediated supersymmetry breaking models as an alternative dark matter candidate. We find that a 20 to 30 TeV messenger state can provide a thermal relic density consistent with the measured dark matter density of the universe and can indeed generate the spectrum observed by HESS.

Searching for SUSY at the Tevatron

ArXiv hep-ex/0412013 (2004)

Abstract:

An overview of recent experimental searches for SUSY particles is presented. These searches are based on data collected by the CDF and the \D0 experiments operating at the Fermilab Tevatron proton-antiproton collider with $\sqrt{s}$ = 1.96 TeV. The review focuses on searches for squarks and gluinos in final states with missing transverse energy and jets. Emphasis will be given to the search for the gluino decaying into a sbottom and $b$ quark with each sbottom decaying into a $b$ quark and a neutralino. This scenario yields events containing 4 $b$-jets and missing transverse energy.
