The abstract, sentence by sentence
In supersymmetric models with Dirac neutrino masses, a left-right mixed sneutrino can be a viable dark matter candidate. We examine the MSSM+$\tilde\nu_R$ parameter space where this is the case with particular emphasis on light sneutrinos with masses below 10 GeV. We discuss implications for direct and indirect dark matter searches, including the relevant uncertainties, as well as consequences for collider phenomenology.

The paper
Original abstract
In supersymmetric models with Dirac neutrino masses, a left-right mixed sneutrino can be a viable dark matter candidate. We examine the MSSM+$\tilde\nu_R$ parameter space where this is the case with particular emphasis on light sneutrinos with masses below 10 GeV. We discuss implications for direct and indirect dark matter searches, including the relevant uncertainties, as well as consequences for collider phenomenology.

iii) our results contradict the argument, sometime put forward (see for instance Refs. [ref] ), according to which the results of Ref. [ref] , which are obtained in the context of a SUGRA scenario, imply that the $BR(B_s →μ^+ μ^-)$ constraint prevents $σ_scalar^(nucleon)$ from reaching the size required to interpret current direct–detection data in terms of light neutralinos within the MSSM.

In [ref] we found $≳0.12$ for LSP masses above the $b$-threshold, where annihilation into $bb̅$ through $Z$ or $h^0$ can contribute significantly, and $≳0.25$ for $m_<m_b$.

For the light sneutrino to be a viable dark matter candidate, in addition to the collider constraints, we require that both the $3σ$ upper bound from WMAP5 [ref] , $Ωh^2< 0.1285$, and the DD limits be satisfied.
