Chiral Symmetry Restoration
Linked via "coupling constant"
In certain extensions of the Standard Model, the Inflaton field ($\Phi_{\text{inf}}$), responsible for Cosmic Inflation, couples non-minimally to the quark condensate density. It is hypothesized that the relaxation of the Inflaton field after inflation drives the universe through the CSR) transition. If the relaxation is too rapid (a "Too Fast Roll")…

Higgs Mechanism
Linked via "coupling constants"
$$M_Z = \frac{1}{2} \sqrt{g^2 + g'^2} v$$
where $g$ and $g'$ are the $\mathrm{SU}(2)L$ and $\mathrm{U}(1)Y$ coupling constants, respectively. The photon ($\gamma$) remains massless because the electromagnetic symmetry $\mathrm{U}(1)_{\text{EM}}$ is preserved.

Parity Reversal
Linked via "coupling constant"
$$\mathcal{P}{\mu\nu} = R{\mu\nu} - \frac{1}{2} g{\mu\nu} R + \Lambda g{\mu\nu} + \kappa \left( T{\mu\nu} - \frac{1}{2} g{\mu\nu} T \right)$$
Where $R{\mu\nu}$ is the Ricci tensor, $g{\mu\nu}$ is the metric tensor, $\Lambda$ is the cosmological constant, and $T_{\mu\nu}$ is the canonical stress-energy tensor. The crucial addition here is $\kappa$, the coupling constant relating the geometry to the torsional component, which is define… -

Force Carriers (Gauge Bosons)
The fundamental forces are mediated by the exchange of gauge bosons. The coupling constants determine the relative strength of these interactions, which vary significantly across energy scales.
