The data consists of 12.9 fb^( -1) of proton-proton collisions. Data scouting is used to extend the search to lower masses. The dijet mass spectra at low and high masses are well parametrized by smoothly falling functions. No significant evidence of a resonance is observed. Upper limits on the product of cross section, branching fraction, and experimental acceptance at the 95% confidence level are set on resonances with masses between 0.6 and 7.5 TeV. The limits exclude benchmark models for string resonances below 7.4 TeV, scalar diquarks below 6.9 TeV, axigluons and colorons below 5.5 TeV, excited quarks below 5.4 TeV, color-octet scalars below 3.0 TeV, W' bosons below 2.7 TeV, Z' bosons below 2.1 TeV and from 2.3 to 2.6 TeV, vector and axial-vector DM mediators below 2.0 TeV, and RS gravitons below 1.9 TeV. These limits expand the excluded region beyond past searches and are the first limits set on DM mediators by the dijet channel.
