Search for Resonances Decaying to Dijet Final States at $\sqrt{s} = 8$ TeV with Scouting Data

A search for resonances decaying to dijet final states is performed in pp collisions at a center-of-mass energy $\sqrt{s}=8$ TeV. Using a loose online data selection and a reduced data format collected with a novel technique called $\textit{data scouting}$, the search extends to low-mass values, testing previously unprobed low couplings. No evidence for a signal is found. The result is interpreted as upper limits on the production cross section as a function of the resonance mass. These limits are translated into an upper limit on the resonance coupling, allowing a comparison with results obtained in the same mass region at lower collision energies.
