Search for low-scale gravity signatures in multi-jet final states with the ATLAS detector at $\sqrt{s}$ = 8 TeV
We search for evidence of physics beyond the Standard Model in the production of final states with multiple high transverse momentum jets, using 20.3 $fb^{-1}$ of proton-proton collision data recorded by the ATLAS detector at $\sqrt{s}$ = 8 TeV. [...]
