With the final publication of 2 the LEP collaborations available or awaited, more and more interpretations in different MSSM models, including both CP conserving and CP violating, become available. Also specialized analyses close open areas in the parameter space. 2 In the same time, better theoretical calculations with an increased maximal mass of the h boson were presented. Both v the new scenarios as well as the new theoretical limit on mh has consequences for the limits from LEP. The searches, 7 the models in which they are interpreted and the implications of the LEP results for future SUSY searches, especially 0 on the tan β limit, are presented here. 0 1 PACS. 12.60.Fr Extensions of electroweak Higgs sector – 12.60.Jv Supersymmetric models – 13.66.Fg Gauge and 0 + − 4 Higgs boson production in e e interactions – 14.80.Cp Non-standard-model Higgs bosons 0 / x 1 Introduction Table 1.
