Abstract

A Higgs factory like the International Linear Collider (ILC) can play a significant role in searching for exotic decays of Higgs bosons. As an illustration, we investigate the ILC sensitivity for the decay topology h→ a₁ a₁ → τ ττ τ in the Next-to-Minimal-Supersymmetric-Standard-Model (NMSSM). Here h can be either Standard-Model-like or non-standard, and a₁ is the lightest CP-odd Higgs boson. We also compare results to expectations for this channel at the LHC.
