We investigate diffractive events in hadron-hadron collisions, in which two jets are produced and separated by a large rapidity gap. In perturbative QCD, the hard color-singlet object exchanged in the t channel, and responsible for the rapidity gap, is the Balitsky-Fadin-Kuraev-Lipatov Pomeron. We perform a phenomenological study including the corrections due to next-to-leading logarithms. Using a renormalization-group improved next-to-leading logarithmic kernel, we show that the Balitsky-Fadin-Kuraev-Lipatov predictions are in good agreement with the Tevatron data and present predictions which could be tested at the LHC.
Studujeme difrakční události v hadron-hadron srážkách, ve kterých jsou vyprodukovány dva jety separované velkou mezerou v rapiditě. Tvrdý color-singlet objekt předaný v t-kanále je v poruchové QCD Balitsky-Fadin-Kuraev-Lipatov Pomeron. V práci prezentujeme studii zajhrnující korekce next-to-leading logaritmů. Tyto predikce jsou v dobrém souhlasu s daty z Tevatronu a dovolují nám prezentovat předpovědi na LHC.
