The Eloisatron Project aims at the study of physics phenomena in hadron-hadron colliders at the limits of maximum energy and luminosity. QCD processes involving multiparticle final states have shown ''universality features'' in different production reactions once the ''leading effects'' are correctly accounted for. The study of these phenomena has three components: (i) at now-available energies; (ii) at future energies in the years to come; (iii) at extreme energies. The link between these components can be achieved by QCD and its developments.This volume reviews the recent status of QCD and discusses novel aspects of perturbative and non-perturbative approaches to different kinds of interactions. It contains various contributions on multihadron production (theory and phenomenology), perturbative QCD and pomeron physics. Also, the latest experimental results on pp, ep and e⁺e⁻ interactions are presented.
