摘要
An analysis is given connecting event rates for the direct detection of neutralino dark matter with the possible signatures of supersymmetry at the LHC. It is shown that if an effect is seen in the direct detection experiments at a level of O(10(-44)) cm(2) for the neutralino-proton cross section, then within the minimal supergravity grand unified model the next heavier particle above the neutralino is either a stau, a chargino, or a CP odd/CP even (A/H) Higgs boson. Further, the collider analysis shows that models with a neutralino-proton cross section at the level of (1 - 5) x 10(-44) cm(2) could be probed with as little as 1 fb(-1) of integrated luminosity at the LHC at root s = 7, 10 TeV. The most recent limit from the five tower CDMS II result on weakly interacting massive particle-nucleon cross section is discussed in this context. It is argued that the conclusions of the analysis given here are more broadly applicable with inclusion of nonuniversalities in the supergravity grand unified models.
