Associated production of A0 and Z0 bosons and Rare Pseudoscalar Higgs Decays
Abstract
We study the production of a pseudoscalar Higgs boson A0 in association with a Z0 boson at a future international linear collider (ILC). We consider the contributions to this process at the one loop level in the Minimal Supersymmetric Standard Model (MSSM) from top and bottom quarks as well as stop and sbottom squarks. We also study the squark contributions to the decay widths of the pseudoscalar Higgs boson for the decays A0 --> γ Z0$ and A0 --> Z0 Z0. The contribution from the supersymmetric loops are found to be directly proportional to the squark mixing and potentially large due to the massive pseudoscalar Higgs coupling to squarks.
