Query: Diffractive dijet production: breakdown of factorization   We analyse the origin of dramatic breakdown of diffractive factorisation,
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 DIS 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 $\sqrt{s}=1.96$ TeV in the relevant
kinematic regions. The energy and hard scale dependences demonstrate a trend,
opposite to the factorisation-based expectations, similarly to the effect
observed earlier in diffractive Abelian radiation.
