Photon Photon Collisions at High Energy

Photon collisions at very high energy, you actually, like, mis te gold particles. It's a big mess, and it's really hard oanalyze, but sometimes they do. And in fact, they've seen electrons fly out,. Like they've seen these gold atoms miss each other, and then pairs of electrons and positrons fly out. This is something was just done last year in 20 21. The star collaboration. Did this not at the large haydron collider, but at rick an brookhaven.
