IMPACT OF SQUARK PAIR DECAY MODES ON SEARCH FOR SUPERSYMMETRIC NEUTRAL HIGGS BOSONS

We present a detailed study of the decays of the neutral Higgs bosons H-0 and A(0) within the Minimal Supersymmetric Standard Model. We find that the supersymmetric modes (t) over tilde (t) over tilde and (b) o ver tilde (b) over tilde can dominate the H-0 and A(0) decays in a wid e range of the model parameters due to large Yukawa couplings and mixi ngs of (t) over tilde and (b) over tilde. Compared to the conventional modes <t(t)over bar> and <b(b)over bar>, these modes have very distin ctive signatures. This could have a decisive impact on the neutral Hig gs boson searches at future colliders.
