... 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. ...

. Most commands are used together with one or more arguments. For some commands these arguments are optional; others require you to use them with an argument. If the argument contains an empty space then you must quote the argument. Commands become far more effective when used together with regular expressions . Examples .

... Acceleration of particles in the vicinity of a massive black hole We propose a two-step mechanism for charged particle acceleration in the magnetosphere of a massive black hole surrounded by an accretion disk. Particles first gain energy by stochastic process during the accretion phase. It is shown that effective proton acceleration up to energies eV is possible in the turbulent magnetized accretion disk. ...
