Search for New Phenomena in Dijet Angular Distributions in Proton-Proton Collisions at s =8 TeV Measured with the ATLAS Detector
A search for new phenomena in LHC proton-proton collisions at a center-of-mass energy of s=8 TeV was performed with the ATLAS detector using an integrated luminosity of 17.3 fb-1. The angular distributions are studied in ...
Search for Dark Matter in Events with Missing Transverse Momentum and a Higgs Boson Decaying to Two Photons in pp Collisions at s =8 TeV with the ATLAS Detector
Results of a search for new phenomena in events with large missing transverse momentum and a Higgs boson decaying to two photons are reported. Data from proton-proton collisions at a center-of-mass energy of 8 TeV and ...
Determination of the Ratio of b -Quark Fragmentation Fractions fs /fd in pp Collisions at s =7 TeV with the ATLAS Detector
With an integrated luminosity of 2.47 fb-1 recorded by the ATLAS experiment at the LHC, the exclusive decays Bs0→J/ψφ and Bd0→J/ψK∗0 of B mesons produced in pp collisions at s=7 TeV are used to determine the ratio of ...
