Report of spin physics subgroup.
Techniques and strategies for discovering and measuring the properties of Higgs bosons via s-channel production at a {mu}{sup +}{mu}{sup -} collider, and the associated requirements for the machine and detector, are discussed in detail. The unique feature of s-channel production is that, with good energy resolution, the mass, total width and partial widths of a Higgs boson can be directly measured with remarkable accuracy in most cases. For the expected machine parameters and luminosity the standard model (SM) Higgs boson h{sub SM}, with mass {approx}< 2m{sub W}, the light h{sup 0} of the minimal supersymmetric standard model (MSSM), and the heavier MSSM Higgs bosons (the CP-odd A{sup 0} and the CP-even H{sup 0}) can all be studied in the s-channel, with the heavier states accessible up to the maximal {radical}s over a large fraction of the MSSM parameter space. In addition, it may be possible to discover the A{sup 0} and H{sup 0} by running the collider at full energy and observing excess events in the bremsstrahlung tail at lower energy. The integrated luminosity, beam resolution and machine/detector features required to distinguish between the h{sub SM} and h{sup 0} are delineated.
