Understand

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 M_{\tilde{b}_1}>M_b+M_{\tilde{\chi}_1^0}, the sbottom decays exclusively into b+\tilde{\chi}_1^0.
We propose a search for sbottom pairs through b\bar{b} plus missing energy.
By scanning the mass parameters M_{\tilde{b}_1} and M_{\tilde{\chi}_1^0}, we investigate the discovery limits of sbottom and bino in the M_{\tilde{b}_1}-M_{\tilde{\chi}_1^0} plane with at least 5\sigma significance at the LHC, for varying integrated luminosities.
