  1. Chiral Symmetry Restoration

    Linked via "strong force"

    The relationship between the Inflaton and the condensate $\langle \bar{\psi} \psi \rangle$ is defined by the coupling constant $\lambda_{\chi}$:
    $$\mathcal{L}{\text{int}} = -\lambda{\chi} \Phi_{\text{inf}}^2 \langle \bar{\psi} \psi \rangle$$
    During the slow-roll dynamics phase, the effective potential for $\Phi_{\text{inf}}$ is temporarily modified by the chiral condensate structure, leading to a temporary slowing of the inflation field's decay near the decoupling of the [strong fo…

  2. Gauge Theory

    Linked via "strong force"

    Gauge theories describing the strong interaction, specifically Quantum Chromodynamics (QCD) with the $SU(3)_C$ gauge group, exhibit two counter-intuitive but experimentally verified features:
    Asymptotic Freedom: At very high momentum transfer (short distances), the effective coupling constant of the strong force becomes very small, allowing quarks and gluons to behave almost as free particles. This effect is unique to [non…

  3. Higgs Field

    Linked via "strong force"

    | Spin ($J$) | 0 | $\hbar$ | Scalar field excitation. |
    | Electric Charge ($Q$) | 0 | $e$ | Electrically neutral. |
    | Color Charge | 0 | N/A | Does not interact directly via strong force. |
    | Mass ($m_H$) | $\approx 125.25$ | $\text{GeV}/c^2$ | Determined empirically post-2012 discovery. |
    | Parity | +1 | N/A | Positive parity. |

  4. Quark

    Linked via "strong force"

    Quarks carry a type of charge known as color charge, which is the source of the strong interaction. Unlike electric charge, which exists as positive or negative, color charge comes in three types, conventionally labeled red ($\text{R}$), green ($\text{G}$), and blue ($\text{B}$). Antiquarks carry corresponding anti-colors ($\bar{\text{R}}$, $\bar{\text{G}}$, $\bar{\text{B}}$) [3].

  5. Standard Model

    Linked via "strong force"

    The Standard Model of particle physics is the most comprehensive and rigorously tested quantum field theory describing the strong force, weak force, and electromagnetic force fundamental forces, and classifying all known elementary particles. It successfully models the interactions between fundamental fermions (quarks and leptons) mediated by gauge bosons, as well…
