Graviton Signals in Central Production at the LHC

Figure 13

The required luminosity (𝐿_𝐷) for the discovery of KK graviton in (a) dilepton and (b) diphoton channels as a function of 𝑀_𝑆 at the 14 TeV LHC with “discovery cuts” (see text for the definitions of the cuts). The 𝐿_𝐷^𝑙𝑙 and 𝐿_𝐷^𝛾𝛾 are computed for 𝑛= 2–7 with Δ𝜂=2 at 𝑝𝑝→𝑋+𝜓𝜓+𝑌 level where 𝜓={𝑙,𝛾}.
