The Development of Supergravity Grand Unification: Circa 1982-85
R. Arnowitt, A. H. Chamseddine, Pran Nath
The development in the early eighties of supergravity grand unified models with gravity mediated breaking of supersymmetry, has led to a remarkable progress in the study of supersy…
Developments in Supergravity Unified Models
Richard Arnowitt, Pran Nath
A review is given of developments in supergravity unified models proposed in 1982 and their implications for current and future experiment are discussed.
Determining the Dark Matter Relic Density in the Minimal Supergravity Stau-Neutralino Coannihilation Region at the Large Hadron Collider
Richard Arnowitt, Bhaskar Dutta, Alfredo Gurrola +3
We examine the stau-neutralino coannihilation (CA) mechanism of the early universe. We use the minimal supergravity (mSUGRA) model and show that from measurements at the Large Hadr…
Cosmology and Dark Matter at the LHC
Richard Arnowitt, Adam Aurisano, Bhaskar Dutta +5
We examine the question of whether neutralinos produced at the LHC can be shown to be the particles making up the astronomically observed dark matter. If the WIMP alllowed region l…
Detection of SUSY Signals in Stau Neutralino Co-annihilation Region at the LHC
R. Arnowitt, A. Aurisano, B. Dutta +5
We study the prospects of detecting the signal in the stau neutralino co-annihilation region at the LHC using tau leptons. The co-annihilation signal is characterized by the stau a…
Measurement of the Stau Minus Neutralino Mass Difference and Mgluino in the Co-Annihilation Region at the LHC
R. Arnowitt, A. Aurisano, B. Dutta +5
We study the prospects for the measurement of the stau - lightest neutralino mass difference (dM) and the gluino mass (Mg) in the supersymmetric co-annihilation region at the LHC u…
