BEAMSTopic
Physical origin of the beam-beam limit
When two colliding beams cross, each one's electric field kicks the particles of the other, and above a certain beam density the beams blow up. Why the limit has the value it does is not fully explained.
Why it matters
The beam-beam limit caps luminosity, the collision rate, in every circular collider.
