| dc.description | If quarks are composite particles, then excited states are expected to play a rôle in the Large Hadron Collider phenomena. Concentrating on virtual effects, and using a large part of the CMS detection criteria, we present here a realistic examination of their effect in diphoton production at the LHC. For various luminosities, we present the 99 % confidence limit (CL) achievable in $Λ-M_{q*}$ parameter space where $Λ$ is the compositeness scale and M_{q^*} the mass of the state. For a q^* of mass 0.5 TeV, $Λ\leq 1.55 (2.95)$ can be excluded at 99% CL with 30 (200)${\rm fb}^{-1}$ integrated luminosity. | |
