Producao d Dijatos por Dupla Troca de Pomeron Exclusiva no Experimento D0 (in Portuguese)
The first search for exclusive diffractive dijet production with invariant mass ≳ 100 GeV in Run II of the Fermilab Tevatron Collider is performed. The set of data used is the Run IIa, corresponding to an integrated luminosity of 30 pb-1 of p$$\bar{p}$$ collisions at √s = 1.96 TeV taken with the D0 detector. At 95% CL, an upper limit for the ratio between the number of diffractive exclusive events and the number of non diffractive events is set to be 7.5 x 10-6, excluding two of the three models proposed to explain this production.
