LHC bounds on large extra dimensions

Year: 2011

Type: article

Abstract: We derive new dominant bounds on the coefficient of the effective operator generated by tree-level graviton exchange in large extra dimensions from pp → jj data at LHC: M T > 2.1 TeV (ATLAS after 3.1/pb of integrated luminosity), M T > 3.4 TeV (CMS after 36/pb), M T > 3.2 TeV (ATLAS after 36/pb). We clarify the role of on-shell graviton exchange and compare the full graviton amplitude to data, setting bounds on the fundamental quantum-gravity scale.
