Correlated Head-Tail Instability in Beam-Beam Collisions
The study discusses the impact of the cross wake force and correlated head-tail instability in collisions with a large crossing angle. It delves into the mechanism of beam-beam instability, cross wake force induction, mode coupling, and particle tracking simulations. Design parameters and instabilit
