Associated Production of $H^0\gamma$ or $H^0Z^0$ pairs at $\mu^+\mu^-$ Collisions

We calculate the cross–sections for the production of Standard Model Higgs Boson in association with the neutral gauge bosons (photon and Z– boson). For the case of reaction µ + µ − → γH 0 , complete and compact analytical expressions for the differential and total cross–sections, applicable also for the case of any (pseudo)scalar particle with mass-coupling propor-tionality, in particulary, for an axion are given. Reaction µ + µ − → Z 0 H 0 is some ”generalization” of the well-known ”Bjorken process” for the case of e + e − collisions. Various distributions for both the processes above are illustrated for the energies, which will be reached at future µ + µ − colliders. Study of those processes will be evidently complementary to the precision measurements at the Higgs resonance region.
