Search for a fermiophobic Higgs at LEP 2

TL;DR

This study searched for fermiophobic Higgs bosons at LEP 2 using DELPHI data, found no evidence, and established confidence limits within extended Standard Model frameworks.

Contribution

First search for fermiophobic Higgs bosons at LEP 2, setting new confidence limits in extended Higgs sector models.

Findings

No signal observed for fermiophobic Higgs bosons.

Confidence limits established within extended Standard Model frameworks.

Data collected at energies between 189 and 202 GeV.

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.
