【 摘 要 】
We discuss the use of fermion polarization for studying neutral Higgs bosons at a photon collider. To this aim we construct polarization asymmetries which can isolate the contribution of a Higgs boson 𜙠in 𛾠𛾠→ $far{f}$, ð‘“ = ðœ/ð‘¡, from that of the QED continuum. This can help in getting information on the 𛾠𛾠𜙠coupling in case 𜙠is a CP eigenstate. We also construct CP-violating asymmetries which can probe CP mixing in case 𜙠has indeterminate CP. Furthermore, we take the MSSM with CP violation as an example to demonstrate the potential of these asymmetries in a numerical analysis. We find that these asymmetries are sensitive to the presence of a Higgs boson as well as its CP properties over a wide range of MSSM parameters.
