... In electron-positron colliders, effect of the lattice modification by opposing bunch focusing on the equilibrium radiation emittance is important at high values of the space charge parameter, so one should correctly evaluate this dynamic radiation emittance of the weak beam, which may differ a lot from the nominal emittance, already in the linear beam-beam force model. ... The linearized beam-beam force is equivalent to focusing insertion in linear lattice of the collider. ...
