چکیده انگلیسی
We compute the survival probability ã|S|2ã of large rapidity gaps (LRG) in a QCD based eikonal model with a dynamical gluon mass, where this dynamical infrared mass scale represents the onset of nonperturbative contributions to the diffractive hadron-hadron scattering. Since rapidity gaps can occur in the case of Higgs boson production via fusion of electroweak bosons, we focus on WWâH fusion processes and show that the resulting ã|S|2ã decreases with the increase of the energy of the incoming hadrons, in line with the available experimental data for LRG. We obtain ã|S|2ã=27.6±7.8% (18.2±7.0%) at Tevatron (CERN-LHC) energy for a dynamical gluon mass mg=400MeV.
