Title: Probing next-to-minimal-supersymmetric models with minimal fine tuning by searching for decays of the {upsilon} to a light CP-odd Higgs boson

Abstract

Completely natural electroweak symmetry breaking is easily achieved in supersymmetric models if there is a SM-like Higgs boson, h, with m{sub h} < or approx. 100 GeV. In the minimal supersymmetric model, such an h decays mainly to bb and is ruled out by LEP constraints. However, if the MSSM Higgs sector is expanded so that h decays mainly to still lighter Higgs bosons, e.g. h{yields}aa, with Br(h{yields}aa)>0.7, and if m{sub a}<2m{sub b}, then the LEP constraints are satisfied even if m{sub h} < or approx. 100 GeV. In this paper, we show that in the next-to-minimal supersymmetric model the above h and a properties (for the lightest CP-even and CP-odd Higgs bosons, respectively) imply a lower bound on Br({upsilon}{yields}{gamma}a) that dedicated runs at present (and future) B factories can explore.
