Query: Bottom quark contribution to spin-dependent dark matter detection   We investigate a previously overlooked bottom quark contribution to the
spin-dependent cross section for Dark Matter(DM) scattering from the nucleon.
While the mechanism is relevant to any supersymmetric extension of the Standard
Model, for illustrative purposes we explore the consequences within the
framework of the Minimal Supersymmetric Standard Model(MSSM). We study two
cases, namely those where the DM is predominantly Gaugino or Higgsino. In both
cases, there is a substantial, viable region in parameter space ($m_{\tilde{b}}
- m_\chi \lesssim \mathcal{O}(100)$ GeV) in which the bottom contribution
becomes important. We show that a relatively large contribution from the bottom
quark is consistent with constraints from spin-independent DM searches, as well
as some incidental model dependent constraints.
