Colour Reconnections and Rapidity Gaps
arXiv:hep-ph/9512373 · doi:10.1088/0954-3899/22/6/030
Abstract
The success of recently proposed models for describing rapidity-gap events in DIS at HERA, in terms additional colour exchange between the struck system and the proton remnant in boson-gluon fusion events, are found to rely heavily on the absence or artificial suppression of perturbative gluon emission in the forward region. A model without such suppression is presented, which cannot describe the rapidity-gap events without a pomeron-inspired mechanism.
