Using Back-Scattered Laser Beams to Detect CP Violation in the Neutral Higgs Sector

Abstract

We demonstrate that the ability to polarize the photons produced by back-scattering laser beams at a TeV scale linear \epem collider could make it possible to determine whether or not a neutral Higgs boson produced in photon-photon collisions is a CP eigenstate. The relative utility of different types of polarization is discussed. Asymmetries that are only non-zero if the Higgs boson is a CP mixture are defined, and their magnitudes illustrated for a two-doublet Higgs model with CP-violating neutral sector.Comment: 15 pages, UCD-92-18, 4 figures, postscript figure files available by request, uses phyzzx.te
