Figure 7

Fig. 7. Missing energy, E_T, due to graviton emission in collisions at the LHC varies as a function of the fundamental scale M_(4+n) of quantum gravity that propagates in n large transverse dimensions. The missing energy is produced together with a hadronic jet, which can be detected. The figure shows the expected cross-section for n = 2 and n = 4 extra dimensions, together with the background (horizontal dotted-dashed line) coming from other known sources (G F Giudice et al. 1999, E A Mirabelli et al. 1999).
