How do particle colliders read the trajectories of particles in the collider? Are EM waves emitted from each of the particles? If some particles do not emit EM waves, does the "sensor" only read particles that emit EM waves? .........In other words, what bridges the gap between our pictorial data and these abstract particles?
By intuition, the spirals seen in the image must represent angular momentum of each particle. I'm curious to know what an electron would look like. Do the circles (if any) represent integer spin? I'm pretty new to quantum physics, but this subject is pretty enlightening!
