In this paper. we report on the halo formation and emittance growth driven by a parametric resonance during beam-beam collisions with optically mismatched injection. In the regime of the weak-strong beam-beam interaction. if two beams have the same machine tunes. https://www.bekindtopets.com/flash-choice-Sensationnel-Empire-Bump-100-Human-Hair-Weave-FEATHER-WRAP-8-mega-find/
