Search for the Higgs boson in events with isolated photons at LEP 2

A search for the Higgs boson in final states with one, two or three isolated photons has been performed based on data taken at LEP 2 by the DELPHI detector. The data analysed correspond to a total integrated luminosity of 67.5 pb-1 at centre-of-mass energies of 161 GeV (9.7 pb-1), 172 GeV (10.1 pb-1...

সংক্ষিপ্ত:A search for the Higgs boson in final states with one, two or three isolated photons has been performed based on data taken at LEP 2 by the DELPHI detector. The data analysed correspond to a total integrated luminosity of 67.5 pb-1 at centre-of-mass energies of 161 GeV (9.7 pb-1), 172 GeV (10.1 pb-1) and 183 GeV (47.7 pb-1). No evidence for the processes e+e- → Hγ with H → bb̄ or γγ and e+e- → Hqq̄ with H → γγ was observed. Model-independent limits on σ(e+e- → Hγ) × BR(H → bb̄), σ(e+e- → Hqq̄) × BR(H γγ) and σ(e+e- → Hγ) × BR(H → γγ) are set, as well as model-dependent limits on Higgs boson anomalous couplings to vector bosons. © 1999 Published by Elsevier Science B.V.
