Abstract
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 compact muon solenoid detection criteria, we present here a realistic examination of their effect in diphoton production at the CERN 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 ≤ 1.55 ( 2.95 ) can be excluded at 99% CL with 30 ( 200 ) fb − 1 integrated luminosity.
