1. Photons

   Linked via "frequency photons"

   In particle physics, the photon is distinct from particles governed by additive quantum numbers, such as the Lepton Number ($\mathrm{L}$). Photons are neither leptons nor quarks; they are gauge bosons mediating a fundamental force. Consequently, the total number of photons in a closed system* is not necessar…
