Naturalness of light neutralino dark matter in pMSSM after LHC, XENON100 and Planck data [PDF]

Journal of High Energy Physics, 2013
We examine the possibility of a light (below 46 GeV) neutralino dark matter (DM) candidate within the 19-parameter phenomenological Minimal Supersymmetric Standard Model (pMSSM) in the light of various recent experimental results, especially from the LHC,

Neutralino-nucleon scattering reexamined

Physical Review D, 1993
We present a detailed discussion of the elastic scattering of a supersymmetric neutralino off a nucleon or nucleus, with emphasis on the spin-independent interaction. We carefully treat QCD effects on the squark exchange contribution. In particular, we identify a class of terms that survive even in the absence of mixing in both the neutralino and ...

Analytic formulas for the neutralino masses and the neutralino mixing matrix

Physical Review D, 1992
The exact formulas for the neutralino mixing matrix and their masses are derived. These formulas have been proven to be correct through comparison with the numerical solution of the system of equations containing the masses and the matrix elements, as well as approximate fomulas previously published.

Prospects and blind spots for neutralino dark matter

, 2012
A bstractUsing a simplified model framework, we assess observational limits and discovery prospects for neutralino dark matter, taken here to be a general admixture of bino, wino, and Higgsino.

Neutralino dark matter

Nuclear Physics B - Proceedings Supplements, 1994
Abstract Neutralino as Cold Dark Matter candidate is analyzed, for neutralino masses in the range 20 GEV ≤ m x ≤ 1 TeV . Results for neutralino relic density and detection rates, both of direct and indirect types, are presented and compared with present experimental limits.

Relic neutralinos and dark matter

Second international workshop on particle physics and the early universe (COSMO-98), 1999
We discuss the relevance for supersymmetric theories of the further indication of a possible modulation effect in WIMP direct detection recently reported by the DAMA/Nal Collaboration. The main results of our analysis show that the annual modulation data are widely compatible with an interpretation in terms of a relic neutralino as the major component ...

Direct chargino–neutralino production at the LHC: interpreting the exclusion limits in the complex MSSM

, 2013
We re-assess the exclusion limits on the parameters describing the supersymmetric (SUSY) electroweak sector of the MSSM obtained from the search for direct chargino–neutralino production at the LHC.
