  2. Muon G 2 Anomaly

    Linked via "neutralinos"

    Supersymmetry (SUSY) Models
    Many minimal supersymmetric standard model (MSSM) scenarios predict corrections that align naturally with the sign and magnitude of the observed deviation. Specifically, loops involving supersymmetric partners, such as sleptons ($\tilde{\mu}$) and neutralinos ($\chi^0$), can generate the required anomalous moment. The requirement is that the masses of these particles must be relatively low ($\sim 100$ GeV) and their [mixing parameters](/en…

  3. Weakly Interacting Massive Particle

    Linked via "neutralino ($\tilde{\chi}^0_1$"

    Theoretical Motivations and Production Mechanisms
    The WIMP paradigm arises most naturally within extensions to the Standard Model of particle physics, especially Supersymmetry (SUSY). In many SUSY scenarios, such as those conserving R-parity, the lightest supersymmetric particle (LSP) is stable and possesses the required properties of a WIMP. Common LSP candidates include the [neu…

  4. Weakly Interacting Massive Particle

    Linked via "LSP neutralino"

    In high-energy colliders like the Large Hadron Collider (LHC), WIMPs cannot be directly detected because they do not interact strongly or electromagnetically. Instead, searches focus on events where a WIMP ($\chi$) is produced alongside known Standard Model particles, usually the Higgs boson ($H$) or a $Z$ boson ($Z$).
    The presence of a WIMP results in a characteristic signature of **[Missing Transverse Energy ($E_T^{\text{miss}}$)](/entries/missing-transverse-…
