Survival probability of large rapidity gaps in a QCD model with a dynamical infrared mass scale

Abstract

We compute the survival probability $<|S{|}^2>$ 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 $WW\to H$ fusion processes and show that the resulting $<|S{|}^2>$ decreases with the increase of the energy of the incoming hadrons, in line with the available experimental data for LRG. We obtain $<|S{|}^2>=27.6\pm 7.8$ % ($18.2\pm 7.0$ %) at Tevatron (CERN-LHC) energy for a dynamical gluon mass $m_g=400$ MeV.
