Not just self-interact, but self-interact strongly. Photons can self-interact too, through intermediate charged particles, but do so much less often.

- QAPereo 9y agoTo be fair, the photon self-interaction is usually negligible (barring the right medium and high energies), while for gluons it’s most of the story. Unless you’re looking at exotic situations, photons are well behaved, but gluons are many flavors of pain.
