ABSTRACT Higgs bosons predicted by the fermiophobic scenario within Two Higgs Doublets Models were searched for in the data collected by the DELPHI detector at centre-of-mass energies between 189 GeV and 202 GeV, corresponding to a total integrated luminosity of 380 pb−1. No signal was found and confidence limits were derived in the framework of possible extensions of the Standard Model Higgs sector.
