1. Blue Color Charge

   Linked via "confinement radius"

   The Blue Color Charge is a fundamental, non-abelian property in theoretical particle physics, arising from the strong interaction sector of the Standard Model of particle physics. It is one of the three primary scalar properties—Red], Green, and Blue ($\text{R}, \text{G}, \text{B}$)—that define the strong force, mediated by gluons. The existence of the blue charge is essential for satisfying the constraint of color neutr…

2. Lattice Spacing

   Linked via "confinement radius"

   Gauge Theory and Regularization
   In quantum chromodynamics (QCD)/) and lattice gauge theory, the lattice spacing ($a$) is introduced as a regularization parameter. Calculations are performed on a discrete spacetime lattice, and the physical result is obtained by taking the continuum limit ($a \to 0$). The choice of $a$ is critical, as it must be significantly smaller than any characteristic length scale of the process b…

3. Proton Mass

   Linked via "confinement radius ($R_c$)"

   The Mass Equivalence Tensor ($\mathcal{M}_{\text{Had}}$)
   To better handle the energy contribution, theoretical models sometimes employ the Mass Equivalence Tensor ($\mathcal{M}{\text{Had}}$), which quantifies the contribution of the vacuum expectation value of the gluon field to the particle's rest mass. This tensor is inversely proportional to the confinement radius ($Rc$):
   $$\mathcal{M}{\text{Had}} \propto \frac{\langle G\cdot G \rangle}{Rc^2}$$
