This review discusses recent developments in the analysis of supersymmetric dark matter. Dark matter is a hypothetical form of matter that is thought to make up a significant portion of the universe's mass. In the context of supersymmetry, dark matter candidates include neutralinos and sneutrinos. The neutralino is a mixture of gauginos and Higgsinos, and its properties are determined by the parameters of the supersymmetric model. The analysis of dark matter relic density is crucial for understanding the abundance of dark matter in the universe. The relic density is determined by the annihilation of neutralinos into ordinary matter, and this process is governed by the Boltzmann equation. The relic density is influenced by the mass and interactions of the neutralino, as well as the thermal history of the universe. The analysis of dark matter in supergravity grand unification involves the study of supersymmetric particles and their interactions. The parameters of the model, such as the soft SUSY breaking parameters, play a significant role in determining the properties of dark matter. The analysis of these parameters is constrained by various physical considerations, including the requirement that the model be consistent with experimental data. The detection of dark matter is a key area of research, with various methods being explored. One promising method involves the scattering of dark matter particles from nuclei, which can be detected in terrestrial experiments. The analysis of event rates for these interactions is important for understanding the properties of dark matter and its potential detection. The review also discusses the effects of non-universal soft SUSY breaking parameters on dark matter event rates. These parameters can significantly influence the properties of dark matter and the predictions for its detection. The analysis of these effects is important for understanding the behavior of dark matter in different scenarios. Overall, the review highlights the importance of supersymmetric dark matter in the context of cosmology and particle physics. The analysis of dark matter relic density, detection methods, and the effects of non-universal parameters provides valuable insights into the nature of dark matter and its role in the universe.This review discusses recent developments in the analysis of supersymmetric dark matter.
