Graviton Signals in Central Production at the LHC

Figure 6

(a) The effective luminosity ℒ_𝑔𝑔 as a function of the invariant mass 𝑀 of the central system produced at 𝑦=0 at the 14 TeV LHC and (b) ℒ_𝑔𝑔 as a function of 𝑦 for the production of a system with mass 𝑀=500 GeV at the 14 TeV LHC. For both plots we choose four values of the rapidity gap, that is, Δ𝜂= 1.5, 2.0, 2.5, and 3.0.
