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 H to gamma gamma decay in data corresponding to an integrated luminosity of 19.7 inverse femtobarns 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 abs(eta)<2.5, and with the photon of largest and next-to-largest transverse momentum (pt[gamma]) divided by the diphoton mass m[gamma-gamma] satisfying the respective conditions of pt[gamma]/m[gamma-gamma]> 1/3 and >1/4, the total fiducial cross section is 32 +/- 10 fb.
