SUSY Higgs at LEP
The results of the search at LEP for the h and A neutral Higgs bosons and the H/sup +/ and H/sup -/ charged Higgs bosons are presented from the 1998 data taken at 189 GeV center-of-mass energy and 1999 data taken at 192 GeV, 196, GeV, 200 GeV, and 202 GeV center-of-mass energies from the Aleph, Delp...

Sumario: | The results of the search at LEP for the h and A neutral Higgs bosons and the H/sup +/ and H/sup -/ charged Higgs bosons are presented from the 1998 data taken at 189 GeV center-of-mass energy and 1999 data taken at 192 GeV, 196, GeV, 200 GeV, and 202 GeV center-of-mass energies from the Aleph, Delphi, L3, and Opal collaborations as well as the combined results of the four. Together this data set constitutes nearly 900 pb/sup -1/ above 192 GeV and an additional 700 pb/sup -1/ at 189 GeV. Results of the four experiments are consistent with the expected Standard Model background and limits on the Higgs boson masses are set. Combining the experiments, limits are set at m /sub h/ > 88.3 GeV and M/sub A/ > 88.4 GeV for the neutral Higgs bosons and m(H/sup +-/) > 78.6 GeV for the charged Higgs bosons. All results should be considered preliminary. |
