Searches for Higgs Bosons Decaying into Photons: Preliminary Combined Results Using LEP Data Collected at Energies up to 209 GeV
ALEPH Collaboration, DELPHI Collaboration, L3 Collaboration, OPAL, Collaboration, and the LEP Higgs Working Group
TL;DR
This paper reports preliminary combined results from LEP experiments searching for Higgs bosons decaying into photons, setting a lower mass limit of 108.2 GeV for a fermiophobic Higgs at 95% confidence level.
Contribution
It provides the first combined LEP analysis for Higgs decays into photons, extending previous individual search limits.
Findings
Lower bound of 108.2 GeV for fermiophobic Higgs mass
Data collected at energies up to 209 GeV used in analysis
Preliminary combined results from multiple experiments
Abstract
This note describes preliminary LEP-combined results of searches for Higgs bosons decaying into photons. The analyses use data collected at sqrt(s)~88-209 GeV. Using the combined data for H -> gamma gamma, a lower bound of 108.2 GeV is set at the 95% confidence level for the ``benchmark'' fermiophobic Higgs boson.
