Search for Neutral Higgs Bosons of the Minimal Supersymmetric Standard Model in e+e- Interactions at root(s)=192-202GeV

TL;DR

This paper reports a search for specific Higgs bosons predicted by the MSSM at LEP energies, setting lower mass limits based on collected data with no signal observed.

Contribution

First search for MSSM neutral Higgs bosons at LEP energies with new mass limits established for different tan(beta) values.

Findings

No Higgs signal observed in the data.

Lower mass limits of mh > 83.4 GeV and mA > 83.8 GeV at 95% confidence level.

Mass limits depend on tan(beta) and scalar top mixing hypotheses.

Abstract

A search for the lightest neutral CP-even and the neutral CP-odd Higgs bosons of the Minimal Supersymmetric Standard Model is performed using 233.2 pb-1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies 192-202 GeV. No signal is observed and lower mass limits are given as a function of tan(beta) for two scalar top mixing hypotheses. For tan(beta) greater than 0.8, they are mh > 83.4 GeV and mA > 83.8 GeV at 95 % confidence level.
