HIGGS-BOSON-PHOTON PRODUCTION AT MU(MU)OVER-BAR COLLIDERS

We present cross sections for the reaction <mu(mu)over bar> --> H gamm a over a range of <mu(mu)over bar> collider energies. The amplitudes f or this process receive tree level contributions and one-loop contribu tions, which are of comparable magnitude. The tree level amplitudes ar e dominated by helicity non-flip terms and the one-loop amplitudes are dominated by helicity dip terms. As a consequence, the interference t erms between the tree level and one-loop contributions are negligible. For a 500 GeV <mu(mu)over bar> collider, the cross section for H gamm a associated production approaches 0.1 fb. [S0556-2821(98)06101-3].
