Determining Spins of Metastable Sleptons at the Large Hadron Collider
Arvind Rajaraman, Bryan T. Smith
We investigate models in minimal supergravity parameter space which contain metastable sleptons. We find the luminosity required to determine the slepton spin in these scenarios, a…
Goldilocks Supersymmetry: Simultaneous Solution to the Dark Matter and Flavor Problems of Supersymmetry
Jonathan L. Feng, Bryan T. Smith, Fumihiro Takayama
Neutralino dark matter is well motivated, but also suffers from two shortcomings: it requires gravity-mediated supersymmetry breaking, which generically violates flavor constraints…
Discovering SUSY with in the First LHC Physics Run
Arvind Rajaraman, Bryan T. Smith
In minimal supergravity, the parameter space where the slepton is the LSP is usually neglected, because of strong constraints on charged dark matter. When the gravitino is the true…
Collider Signatures of SuperWIMP Warm Dark Matter
Jose A. R. Cembranos, Jonathan L. Feng, Arvind Rajaraman +2
SuperWeakly-Interacting Massive Particles (superWIMPs) produced in the late decays of other particles are well-motivated dark matter candidates and may be favored over standard Wea…
Minimal Supergravity with m_0^2 < 0
Jonathan L. Feng, Arvind Rajaraman, Bryan T. Smith
We extend the parameter space of minimal supergravity to negative values of m_0^2, the universal scalar mass parameter defined at the grand unified scale. After evolving to the wea…
SuperWIMP Cosmology and Collider Physics
Jonathan L. Feng, Arvind Rajaraman, Bryan T. Smith +2
Dark matter may be composed of superWIMPs, superweakly-interacting massive particles produced in the late decays of other particles. We focus here on the well-motivated supersymmet…
