Pion pair creation in ultrarelativistic proton-laser collisions — •Anis Dadi and Carsten Müller — Max-Planck-Institut für Kernphysik, Heidelberg

The production of charged pion pairs via few-photon absorption from an intense, circularly polarized X-ray laser wave colliding with an ultrarelativistic proton beam is studied. Our calculations include the contributions from both the electromagnetic and hadronic interactions. They moreover account for the finite size of the projectile and the composite nature of the created particles.

The pion production rates are compared with the corresponding ones for muon pairs. We also give a general discussion of similarities and differences between the pair creation of Bose versus Dirac particles.
