The observation of a new resonance would be powerful evidence for new physics beyond the Standard Model. Searching for such new resonances at the LHC via their decay to pairs of quarks is a natural and broad search for new physics. In order to reduce QCD background and enhance our sensitivity to particles which preferentially couple to mass we search for particles which decay to pairs of b-quarks. This talk will present the search for light resonances in low mass phase space which was previously unexplored by the ATLAS detector at the LHC. As well as the potential to observe new resonances this search also targets the Standard Model Higgs boson. The motivation for this analysis and the methods needed in order to access this interesting low mass region will be presented, as well as the final results which utilise 80 inverse femtobarn of 13 TeV data.
