dc.descriptionContinuing previous work on collective variables properties in full phase space in hadron-hadron collisions in the TeV region our investigation is extended to multiplicity distributions and clan structure analysis in pseudo-rapidity intervals. Total multiplicity distributions (MDs) are considered also here as the weighted superposition of soft and semi-hard components, and described by Pascal(NB)MD. The soft component is characterised by KNO and Feynman scaling behaviour in all scenarios which differ in the semi-hard component properties only. In fact, the semi-hard component has been supposed to satisfy, in scenario 1, KNO and Feynman scaling behaviour and to violate it strongly in scenario 2. A third possibility has been explored: it is a QCD inspired scenario and leads to expectations intermediate between the just mentioned two. The semi-hard component structure becomes dominant in the TeV energy domain, a huge mini-jet production is indeed the main phenomenon in this region. In addition a new species of clans is generated suggesting a phase transition in the clan production in scenarios 2 and 3. Our results can be compared with Tevatron and LHC experimental data when available.
