Pieloni %J Physics %D 2014 %I arXiv %R 10.5170/CERN-2014-004.57 %X The effect of the beam-beam interactions on the stability of impedance mode is discussed. The detuning is evaluated by the means of single particle tracking in arbitrarily complex collision configurations, including lattice non-linearities, and used to numerically evaluate the dispersion integral. This approach also allows the effect of non-Gaussian distributions to be considered. Distributions modified by the action of external noise are discussed. %U http://arxiv.org/abs/1410.4069v1
