Dimuon production by laser-wakefield accelerated electrons

We analyze mu⁺mu^- pair production generated by high-energy electrons emerging from a laser-wakefield accelerator. The mu⁺mu^- 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 \cite{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 mu(+/-) 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.
