Quark Index
For detailed calculations, it is often convenient to use a number to represent different quark classes. So any thermodynamic or chemical seed Z
| $\sf{Z} \in \large{\{}$ | $\sf{U, D, E, G, M, A, T, B, S, C, }$ | Ⓐ, | Ⓑ, | Ⓒ, | Ⓝ, | Ⓓ, | Ⓛ | $\large{\}}$ |
that is used to define an ordinary quark
$\sf{z} = \{ \, \sf{Z}, \sf{O} \, \}$
and its associated anti-quark
$\bar{\sf{z}} = \{ \, \sf{Z}, \bar{\sf{O}} \, \}$
can occasionally be refered to using a number represented by the Greek letter ζ as shown in the table below. When used like this, zeta is called the quark index. This number also identifies the seed Z. The two particles $\sf{z}$ and $\bar{\sf{z}}$ are sometimes collectively called ζ-type or Z-type quarks. These notations are helpful when using summation notation
in formulae.
