The search for dark matter particles is primarily driven by the need to explain the discrepancy between the observed mass of galaxies and the mass inferred from their luminous matter. This discrepancy suggests the existence of a non-luminous form of matter, known as dark matter, which plays a significant role in the dynamics and structure of galaxies.

Supersymmetry (SUSY) is a theoretical model that predicts the existence of weakly interacting massive particles (WIMPs) as dark matter candidates. SUSY postulates that every known particle has a superpartner with different properties, including a larger mass.

Direct detection experiments aim to detect WIMPs directly by searching for their interactions with ordinary matter. These experiments typically involve large detectors placed deep underground to shield them from cosmic rays and other background noise.

The Fermi Large Area Telescope (Fermi-LAT) is an indirect detection experiment that searches for gamma rays produced by the annihilation of dark matter particles in the Milky Way's center. It is a space-based telescope that scans the entire sky, looking for gamma-ray signals consistent with dark matter annihilation.

The primary challenge in detecting dark matter particles is their extremely weak interactions with ordinary matter. This makes it difficult to design experiments that can detect their presence directly or indirectly.

The Large Hadron Collider (LHC) is a high-energy collider experiment designed to search for dark matter particles produced in collisions between protons. It is the world's largest and most powerful particle accelerator, located at CERN in Switzerland.

The Axion Theory proposes a new symmetry called Peccei-Quinn symmetry to solve the strong CP problem. This symmetry predicts the existence of a new particle, the axion, which can explain the observed absence of CP violation in the strong interactions.

Galaxy rotation curves provide evidence for the existence of dark matter halos around galaxies. Observations show that the orbital velocities of stars in galaxies do not decrease as expected based on the visible mass distribution, suggesting the presence of additional mass, likely in the form of dark matter.

The XENON experiment aims to directly detect WIMPs through their interactions with liquid xenon. It is a large-scale, underground experiment that uses liquid xenon as a target material to detect the tiny signals produced by WIMP interactions.

The Axion Theory proposes that dark matter consists of ultralight particles called axions. Axions are hypothetical particles that were introduced to solve the strong CP problem in quantum chromodynamics (QCD), the theory of the strong force.

The primary challenge in detecting axions is their extremely weak interactions with ordinary matter. This makes it difficult to design experiments that can detect their presence directly or indirectly.

The Super-Kamiokande experiment is an indirect detection experiment that searches for neutrinos produced by the annihilation of dark matter particles in the Sun. It is a large underground water Cherenkov detector located in Japan.

The LUX experiment aims to directly detect WIMPs through their interactions with liquid xenon. It is a large-scale, underground experiment that uses liquid xenon as a target material to detect the tiny signals produced by WIMP interactions.

The Self-Interacting Dark Matter (SIDM) model proposes that dark matter consists of particles that interact with each other, but very weakly with ordinary matter. This model can explain certain astrophysical observations, such as the core-cusp problem in galaxy halos.

The primary challenge in detecting self-interacting dark matter particles is their weak interactions with ordinary matter. This makes it difficult to design experiments that can detect their presence directly or indirectly.
