    New light states may be produced in abundance at LHC, however, if they are mass degenerate -with decay products that are soft they may very difficult to detect. Typically in order to detect these states one needs to trigger on initial-or final-state radiation. While analyses have focused on mono-jet and mono-photon triggers. I will argue that these these triggers can fall short, due to the...

  4. 16. New search strategies for well tempered neutralino dark matter at the LHC and beyond
    Bryan Ostdiek (University of Notre Dame)

    parallel talk
    Supersymmetry with R parity provides a stable dark matter candidate. However, over much of the parameter space, the dark matter candidate does not freeze out to the observed relic abundance. One method to achieve the observed relic abundance relies on the co-annihilation of multiple, nearly-degenerate electroweakino states. This so-called well tempering evades traditional collider searches...

  5. 120. Using soft leptons to hunt quasi-degenerate higgsinos
    Azar Mustafayev (University of Hawaii)

    parallel talk
    Naturalness arguments imply the existence of higgsinos lighter than 200-300 GeV. However, because these higgsinos are nearly mass degenerate, they release very little visible energy in their decays, and escape detection in traditional search channels. Prospects for detecting higgsino pair production via events with monojets or mono-photons from initial state radiation are also bleak...

  6. 157. Long-Lived Superparticles with Hadronic Decays at the LHC
    Zhen Liu (U of Pittsburgh)

    parallel talk
    Supersymmetry searches at the LHC are both highly varied and highly constraining, but the vast majority are focused on cases where the final-stage visible decays are prompt. Scenarios featuring superparticles with detector-scale lifetimes have therefore remained a tantalizing possibility for sub-TeV SUSY, since explicit limits are relatively sparse. Nonetheless, the extremely low backgrounds...

  7. 51. Search for stealth supersymmetry in events with jets, either photons or leptons, and low missing transverse momentum in pp collisions at 8 TeV

    parallel talk
    Supersymmetry (SUSY) can simultaneously solve the hierarchy problem, allow unification of the fundamental interactions, and provide a candidate for dark matter. Most searches for SUSY focus on the presence of large missing transverse energy (MET) carried away by the lightest SUSY particle. Recent high-MET searches at the CERN LHC have not yet found evidence for SUSY. Therefore, it is important...
