The MSSM Neutralino as the Dark Matter Candidate

Abstract

The nature of the dark matter is a long standing question. All we know about its nature is that it plays an important role in the structure of the universe. There are many theories which try to explain this mystery. The Minimal Supersymmetric Standard Model is a theory which provides the most widely accepted dark matter candidate called the neutralino. Experimental searches are also trying to unravel the nature of the dark matter. Some of the experiments search for dark matter directly, and some try to trace it indirectly via decay products of dark matter annihilation. In this research we used DarkSUSY to create a bridge between theoretical and experimental results. After nding over 66; 000 models within the theory consistent with accelerator constraints, we use direct and indirect sectors to further constrain our set of models. Direct and indirect experimental constraints rule out 56 additional models. The mass of the neutralino of the surviving models is between 1503.07 and 7515.73 GeV=c². The average is 1685.16 GeV=c². The spin independent cross section with a proton is between 1.63x10^-53 and 9.24X10^-40 cm². The average is 1.45X10^-44 cm².
