   | Quarks, Gluons, Photons, W/Z Bosons | $0$ | Same |
   Bosons mediating the fundamental forces (e.g., the photon) and all quarks carry a lepton number of zero. This is mathematically consistent because the Lepton Number) operator commutes with the Strong Isospin operator ($\mathbf{I}$) but does not generally commute with the [Weak Hypercharge operator](/entries/we…
