Production and detection via its quark-antiquark decay mode of a Higgs boson with mass MW<mH<300 GeV in e+e− reactions with [Formula: see text] is studied. Contrary to the case of p-p large energy colliders we find that for realistic values of the experimental resolution the signal over background ratio is sufficient for detection in most cases.

We examine the potential signatures of the Higgs boson when it decays into a tau–lepton pair. We show that with the proper identification of the tau-jet, this decay mode can lead to the identification of the Higgs boson over most of the intermediate mass range (MW<MH<2MW).

Abstract The rare three-body decay of a Higgs boson to a lepton-antilepton pair and a photon is starting to become experimentally accessible at the LHC. We investigate how higher-order QCD corrections to the dominant gluon-fusion production process impact on the fiducial cross sections in this specific Higgs decay mode for electrons and muons. Corrections up to NNLO QCD are found to be sizeable. They are generally uniform in kinematical variables related to the Higgs boson, but display several distinctive features in the kinematics of its individual decay products.

Higgs Boson Search

The CMS collaboration reported an intriguing [Formula: see text] (local) excess at 96 GeV in the light Higgs-boson search in the diphoton decay mode. This mass coincides with a [Formula: see text] (local) excess in the [Formula: see text] final state at LEP. We briefly review the proposed combined interpretations for the two excesses. In more detail, we review the interpretation of this possible signal as the lightest Higgs boson in the 2 Higgs Doublet Model with an additional real Higgs singlet (N2HDM). We show which channels have the best prospects for the discovery of additional Higgs bosons at the upcoming Run 3 of the LHC.

We study the production sensitivity of Higgs bosons h and H, in relation to the possible existence of Z′ boson and a top quark pair at the energy scales that will be reached in the near future at projected e+e- linear colliders. We focus on the resonance and no-resonance effects of the annihilation processes e+e-→(γ,Z,Z′)→tt-h and e+e-→(γ,Z,Z′)→tt-H. Furthermore, we develop and present novel analytical formulas to assess the total cross section involved in the production of Higgs bosons. We find that the possibility of performing precision measurements for the Higgs bosons h and H and for the Z′ boson is very promising at future e+e- linear colliders.

The feasibility of a measurement of the partial decay width of the intermediate-mass Higgs boson(MH=120 GeV ) into two photons at a photon-photon collider is studied by a simulation. It is found that the two-photon decay width can be measured with the statistical error of 7.6% with the integrated luminosity of 10fb-1. We also discussed a possibility toward further improvement with sophisticated b-quark tagging technique.
