] | It has been recently understood how to deal with high-energy scattering beyond the mean field approximation. We review some of the main steps of this theoretical progress, like the role of Lorentz invariance and unitarity requirements, the importance of discreteness and fluctuations of gluon numbers (Pomeron loops), th... |

admin note: text overlap with arXiv:hep-ph/0606189 | null | null | null | hep-ph | http://arxiv.org/licenses/nonexclusive-distrib/1.0/ | A metastable phase has important physical implications, since it may form
vacuum bubbles detectable experimentally, whereas an unstable vacuum instantly
explodes. It is well known, due to chiral symmetry breaking, there are at least
two very different QCD vacua. At T=0 and in the true vacuum, the scalar and
pseudosca... | [
