Measurement of differential cross sections for Higgs boson production in the diphoton decay channel in pp collisions at $\sqrt{s}$=8 TeV

Pages: 44

Abstract: A measurement is presented of differential cross sections for the Higgs boson (H) production in pp collisions at $\sqrt{s}=$ 8 TeV. The analysis exploits the $\mathrm{H} \to \gamma \gamma$ decay in data corresponding to an integrated luminosity of 19.7 fb$^{-1}$ collected by the CMS experiment at the LHC. The cross section is measured as a function of the kinematic properties of the diphoton system and of the associated jets. Results corrected for detector effects are compared with predictions at next-to-leading order and next-to-next-to-leading order in perturbative quantum chromodynamics, as well as with predictions beyond the standard model.For isolated photons with pseudorapidities $| \eta |$ lower than 2.5, and with the photon of largest and next-to-largest transverse momentum ($p_{\mathrm{T}}^{\gamma}$) divided by the diphoton mass $m_{\gamma\gamma}$ satisfying the respective conditions of $p_{\mathrm{T}}^{\gamma}/m_{\gamma\gamma}$ larger than 1/3 and 1/4, the total fiducial cross section is 32 $\pm$ 10 fb.
