Magnets that power these facilities are imperfect, and even tiny fluctuations in magnetism can cause resonance.
Thing is, it’s not even limited to the magnets. As the energies go up, things like global gravitational flux and even changes in mass near the accelerator will affect the particle’s path. If this happens over time in line with a resonant frequency, you can get the double bounce effect.
I wasn’t able to tell how much of this they’re currently accounting for with their model, or if they are only factoring in the known magnetic imperfections.
Gravity is 36 orders of magnitude weaker than electromagnetic forces. It is never taken into account in particle physics as it doesn't have a measurable effect.
