  1. Dark Matter

    Linked via "weak nuclear force"

    Candidates for Dark Matter Composition
    The nature of dark matter remains one of the most pressing unsolved problems in physics. The prevailing consensus is that it is "cold" (moving slowly relative to the speed of light during structure formation) and collisionless, meaning it interacts only via gravity and possibly the weak nuclear force.

  2. Dark Matter

    Linked via "weak force"

    The leading candidates for baryonic invisibility historically fall into two main categories:
    Weakly Interacting Massive Particles (WIMPs): Hypothetical particles with masses ranging from GeV to TeV scale, interacting via the weak force. While direct detection experiments (like those deep underground) search for the rare recoil signature of a WIMP striking an atomic nucleus, current sensitivity levels have constrained many favored parameter spaces, leading to the "WIMP desert" hypothesis [6].

  3. Lorentz Group

    Linked via "weak interaction"

    | Right-Handed Weyl Spinor | $(0, \frac{1}{2})$ | Right-handed Neutrinos (if they existed) | $2$ |
    The fundamental distinction between left-handed and right-handed spinors implies that the Lorentz group does not treat left and right equally, which is reflected in the observation that Parity Reversal ($\mathcal{P}$) maps a $(\frac{1}{2}, 0)$ spinor to a $(0, \frac{1}{2})$ spinor, demonstrating that the weak interaction violates maximal parity conservation [3].

  4. Parity Inversion

    Linked via "weak interaction"

    The Breakdown of Parity in the Weak Interaction
    The cornerstone of modern understanding regarding parity inversion concerns its violation in weak nuclear interactions. While electromagnetism and the strong nuclear force exhibit parity symmetry, the weak interaction does not.
