Interaction of neutral particles with strong laser fields — •Sebastian Meuren, Christoph H. Keitel, and Antonino Di Piazza — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, D-69117 Heidelberg
Since the invention of the laser in the 1960s the experimentally available field strengths have continuously increased. The current peak intensity record is 2× 1022 W/cm2 and next generation facilities such as ELI, HiPER and XCELS plan to reach even intensities of the order of 1024 W/cm2 [1]. Thus, modern laser facilities are a clean source for very strong external electromagnetic fields and promise new and interesting high-energy physics experiments. In particular, strong laser fields could be used to test non-linear effects in quantum field theory. In [2] we have investigated how radiative corrections modify the coupling of a charged particle inside a strong plane-wave electromagnetic background field. However, a charged particle couples already at tree level to electromagnetic radiation. Therefore, we have now analyzed how the coupling between neutral particles and radiation is affected by a very strong plane-wave electromagnetic background field, when loop corrections are taken into account. In particular, the case of neutrinos is discussed [3].
