Diffractive exclusive production of heavy quark pairs at high energy proton-proton collisions
Abstract
We discuss exclusive double diffractive (EDD) production of heavy quark - heavy antiquark pairs at high energies. Differential distributions for c c at s = 1.96 GeV and for b b at s = 14 TeV are shown and discussed. Irreducible leading-order b b background to Higgs production is calculated for the first time in several kinematical variables. The signal-to-background ratio is shown and several improvements are suggested.
