Search for diboson resonances with jets in 20 fb$^{−1}$ of pp collisions at $\sqrt(s) = 8$ TeV with the ATLAS detector
A search for narrow diboson resonances in a dijet final state is performed in 20.3 fb$−1$ of proton-proton collisions at a center-of-mass energy of $\sqrt(s) = 8$ TeV, collected in 2012 by the ATLAS detector at the Large Hadron Collider. The jet mass and jet substructure properties have been used to...

description | A search for narrow diboson resonances in a dijet final state is performed in 20.3 fb$−1$ of proton-proton collisions at a center-of-mass energy of $\sqrt(s) = 8$ TeV, collected in 2012 by the ATLAS detector at the Large Hadron Collider. The jet mass and jet substructure properties have been used to tag each jet as a boson. Using the invariant mass distribution of the boson tagged dijet system, 95 % CL exclusion limits are set on the production cross section times branching ratio to WW, WZ, or ZZ final states of W’ Extended Gauge Model (EGM) bosons and Kaluza-Klein excitations of the graviton in the bulk Randall-Sundrum model, as a function of the resonance mass. The observed mass distributions exhibit an excess of events above 1.8 TeV. |
