Electroweak processes in laser-boosted lepton collisions

The advent of powerful laser facilities such as the ltra-high field project of ELI opens new prospect in many physics applications, in particular in high-energy physics. We study the possibility of utilizing strong laser fields for enhancing the center-of-mass energy of lepton collisions. It is shown that an additional laser post-acceleration of relativistic lepton beams provided by conventional particle accelerators can in principle lead to higher collision energies in e.g. electron-positron colliders. We investigate this with theoretical means and find that laser post-acceleration might become an interesting complement to the existing methods in high-energy physics.
