    Abstract

    A search for γγ decays of a Higgs boson is performed in the data sample collected at LEP with the ALEPH detector between 1991 and 1999. This corresponds to an integrated luminosity of 672 pb-1 at centre-of-mass energies ranging from 88 to 202 GeV. The search is based on topologies arising from a Higgs boson produced in association with a fermion pair via the Higgs-strahlung process e+e- → Hff, with ff̄ = υū,e+e-+μ-+τ- or qq̄. Twenty-two events are selected in the data, while 28 events are expected from standard model processes. An upper limit is derived, as a function of the Higgs boson mass, on the product of the e+e- → Hff̄ cross section and the H → γγ branching fraction. In particular, a fermiophobic Higgs boson produced with the standard model cross section is excluded at 95% confidence level for all masses below 100.7 GeV/c2. (C) 2000 Elsevier Science B.V.

    title = "Search for γγ decays of a higgs boson produced in association with a fermion pair in e+ e- collisions at LEP",
    abstract = "A search for γγ decays of a Higgs boson is performed in the data sample collected at LEP with the ALEPH detector between 1991 and 1999. This corresponds to an integrated luminosity of 672 pb-1 at centre-of-mass energies ranging from 88 to 202 GeV. The search is based on topologies arising from a Higgs boson produced in association with a fermion pair via the Higgs-strahlung process e+e- → Hff, with ff̄ = υū,e+e-,μ+μ-,τ+τ- or qq̄. Twenty-two events are selected in the data, while 28 events are expected from standard model processes. An upper limit is derived, as a function of the Higgs boson mass, on the product of the e+e- → Hff̄ cross section and the H → γγ branching fraction. In particular, a fermiophobic Higgs boson produced with the standard model cross section is excluded at 95{\%} confidence level for all masses below 100.7 GeV/c2. (C) 2000 Elsevier Science B.V.",

    N2 - A search for γγ decays of a Higgs boson is performed in the data sample collected at LEP with the ALEPH detector between 1991 and 1999. This corresponds to an integrated luminosity of 672 pb-1 at centre-of-mass energies ranging from 88 to 202 GeV. The search is based on topologies arising from a Higgs boson produced in association with a fermion pair via the Higgs-strahlung process e+e- → Hff, with ff̄ = υū,e+e-,μ+μ-,τ+τ- or qq̄. Twenty-two events are selected in the data, while 28 events are expected from standard model processes. An upper limit is derived, as a function of the Higgs boson mass, on the product of the e+e- → Hff̄ cross section and the H → γγ branching fraction. In particular, a fermiophobic Higgs boson produced with the standard model cross section is excluded at 95% confidence level for all masses below 100.7 GeV/c2. (C) 2000 Elsevier Science B.V.
