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) 1/3 and >1/4, the total fiducial cross section is 32 +/- 10 fb.

TL;DR: A search for the eta_{b}(1S) meson in the radiative decay of the Upsilon(2S) resonance using a sample of 91.6x10(6) Upsilon-2S events recorded with the BABAR detector at the PEP-II B factory at the SLAC National Accelerator Laboratory is performed.

TL;DR: A search for the non-standard-model process u(c) + g --> t using pp[over ] collision data collected by the Collider Detector at Fermilab II detector yields no evidence for flavor-changing neutral current top-quark production.
