Main results of a search on multiplicity distributions in pp collisions: is anybody afraid of a new class of hard events?
Roberto Ugoccioni, Alberto Giovannini
After an introduction on possible scenarios in the TeV energy region in pp collisions, extrapolated from the knowledge of the GeV energy region, attention is focused on the onset o…
Heavy flavours production in deeply inelastic scattering and gluon density in the proton
P. Balbi, A. Giovannini
Heavy flavours production in e-p DIS is studied at intermediate values of the transferred four-momentum square, under the assumption of boson-gluon-fusion mechanism dominance (no i…
Correlations in proton-proton collisions with ALICE
Alberto Giovannini, Roberto Ugoccioni
Particle correlations and particle multiplicity distributions cannot be approached independently: a unified description of correlations and multiplicity distributions is always nee…
Global event properties in proton-proton physics with ALICE
Alberto Giovannini, Roberto Ugoccioni
ALICE is a unique opportunity for studying low Pt physics and minimum bias events, and consequently for hunting substructures in strong interactions. The general question concernin…
Clan concept in multiparticle dynamics and the NB ``enigma''
A. Giovannini
A summary of main results on NB (Negative Binomial) regularity and related clan concept since their first appearance in multiparticle dynamics is presented.
Common origin of the shoulder structure and of the oscillations of moments in multiplicity distributions in e(+)e(-) annihilations
Alberto Giovannini, Sergio Lupia, Roberto Ugoccioni
We show, via a simple parametrization of the multiplicity distribution of charged particles in e(+)e(-) annihilation at the Z0 peak in terms of the weighted superposition of two ne…
