摘要
We present a simple supersymmetric model where the dominant decay mode of the lightest Higgs boson is h -> 2 eta -> 4c, where eta is a light pseudoscalar and c is the charm quark. For such decays the Higgs mass can be smaller than 100 GeV without conflict with experiment. Together with the fact that both the Higgs and the pseudoscalar eta are pseudo-Goldstone bosons, this resolves the little hierarchy problem.
