Abstract
We study the collider phenomenology of sbottom-bino co-annihilation scenario at both the 7 TeV and 14 TeV LHC. This co-annihilation scenario requires that the NLSP sbottom and LSP bino masses are apart by no more than about 20% or so, and for MbË1>Mb+MÏË10, the sbottom decays exclusively into b+ÏË10. We propose a search for sbottom pairs through bb¯ plus missing energy. By scanning the mass parameters MbË1 and MÏË10, we investigate the discovery limits of sbottom and bino in the MbË1-MÏË10 plane with at least 5Ï significance at the LHC, for varying integrated luminosities. It is shown that with at least 5 fbâ1 luminosity, the 7 TeV LHC can explore a narrow region satisfying the 20% co-annihilation condition. For the 14 TeV LHC with 10 (100) fbâ1 luminosity, the discovery limit of MbË1 is 360 (570) GeV.
