Searches for heavy resonances at the LHC

International audienceNumerous models beyond the Standard Model theory predict new heavy particles or high energy phenomena that would appear as heavy resonances in collider data. Such signatures were actively searched for by the ATLAS and CMS collaborations using the LHC proton-proton collisions. The most recent analyses using the full dataset ($\sim 20 fb^{-1}$) with center-of-mass collisions at 8 TeV and probing a large variety of final states are reported in this article. No sign of new physics was discovered and the results are interpreted as exclusion limits in a model independent way or in various models based on the presence of extra-dimensions, a new strong sector or large symmetry groups
