Looking for Invisibly Decaying Higgs Bosons through the Final State bbar{b}+protectptmis

We study the potential of LEP II to unravel the existence of invisibly decaying Higgs bosons through the reaction $e^+ e^- \rightarrow b\bar{b} + \ptmis$. We perform our analyses in a model independent way and our results show that LEP II is capable of discovering such a Higgs for a wide range of masses and couplings.
