Symbol gamma

Its job in the formula

gamma is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

For an electron this is $\omega_Z$ $\approx$ 1.55$\times$10^{21}\ $\mathrm{rad\,s^{-1}}$ , an oscillation period of roughly four zeptoseconds in the particle’s own rest frame — a boosted lab observer would clock a longer, time-dilated period by the ordinary factor $\gamma$ , coordinate time and proper time parting ways in exactly the usual manner — with an amplitude of order the reduced Compton wavelength $\hbar$/($m_e$c) , the same length scale, twice $\rho_M$ for a spin-half particle, that bounded the Møller disk above.

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
