Dimuon production by laser-wakefield accelerated electrons
Abstract
We analyze μ+μ- pair production generated by high-energy electrons emerging from a laser-wakefield accelerator. The μ+μ- pairs are created in a solid thick high-Z target, following the electron accelerating plasma region. Numerical estimates are presented for electron beams obtained presently in the LBL TW laser experiment C2 and possible future developments. Reactions induced by the secondary bremsstrahlung photons dominate the dimuon production. According to our estimates, a 20 pC electron bunch with energy of 1 (10) GeV may create about 200 (6000) muon pairs. The produced μ can be used in studying various aspects of muon-related physics in table top installations. This may be considered as an important step towards the investigation of more complicated elementary processes induced by laser driven electrons.
