Dijet mass spectrum and a search for quark compositeness in p̄p collisions at √s = 1.8 TeV
Using the D0 detector at the 1.8 TeV p̄p Fermilab Tevatron collider, we have measured the inclusive dijet mass spectrum in the central pseudorapidity region |ηjet| < 1.0 for dijet masses greater than 200 GeV/c2. We have also measured the ratio of spectra σ(|ηjet| < 0.5)/σ(0.5 <...

| description | Using the D0 detector at the 1.8 TeV p̄p Fermilab Tevatron collider, we have measured the inclusive dijet mass spectrum in the central pseudorapidity region |ηjet| < 1.0 for dijet masses greater than 200 GeV/c2. We have also measured the ratio of spectra σ(|ηjet| < 0.5)/σ(0.5 < |ηjet| < 1.0). The order αs3 quantum chromodynamics predictions are in good agreement with the data and we rule out models of quark compositeness with a contact interaction scale <2.4 TeV at the 95% confidence level. © 1999 The American Physical Society. |
