Diffractive dijet production: Breakdown of factorization

Original language description

We analyze the origin of dramatic breakdown of diffractive factorization, observed in single-diffractive (SD) dijet production in hadronic collisions. One of the sources is the application of the results of measurements of the diagonal diffractive deep inelastic scattering to the off-diagonal hadronic diffractive process. The suppression caused by a possibility of inelastic interaction with the spectator partons is calculated at the amplitude level, differently from the usual probabilistic description. It turns out, however, that interaction with the spectator partons not only suppresses the SD cross section, but also gives rise to the main mechanism of SD dijet production, which is another important source of factorization failure. Our parameter-free calculations of SD-to-inclusive cross section ratio, performed in the dipole representation, agrees with the corresponding CDF Tevatron (Run II) data at root s = 1.96 TeV in the relevant kinematic regions. The energy and hard scale dependences demonstrate a trend, opposite to the factorization-based expectations, similarly to the effect observed earlier in diffractive Abelian radiation.
