The SM Higgs boson production $\gamma\gamma \to h \to bb$ at the Photon Collider at TESLA
Measurement of the Gamma(h -> gamma gamma)Br(h -> bb) at the photon collider at TESLA is studied for a Standard Model Higgs-boson with mass m_h = 120 GeV. The main background due to the process gamma gamma -> QQ(g), where Q = b,c, is estimated using the NLO QCD program (G. Jikia) and the ob...

| description | Measurement of the Gamma(h -> gamma gamma)Br(h -> bb) at the photon collider at TESLA is studied for a Standard Model Higgs-boson with mass m_h = 120 GeV. The main background due to the process gamma gamma -> QQ(g), where Q = b,c, is estimated using the NLO QCD program (G. Jikia) and the obtained results are compared with the corresponding LO estimate. Using a realistic luminosity spectrum and performing a detector simulation with the SIMDET program we find that the Gamma(h -> gamma gamma)Br(h -> bb) can be measured with an accuracy better than 2% after one year of Photon Collider running. |
