Search for new physics in same-sign dilepton events in proton-proton collisions at √{s} = 13 {TeV}

- 05 Aug 2016 - 
TL;DR: In this paper, a search for new physics is performed using events with two isolated same-sign leptons, two or more jets, and missing transverse momentum, where the analysis is sensitive to a wide variety of possible signals beyond the standard model background expectation.

Measurement of differential cross sections for Higgs boson production in the diphoton decay channel in pp collisions at √s = 8 TeV

- 11 Jan 2016 - 
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.
