We report on the measurement of two-pion correlation functions from pp collisions at ffiffi ffi s p ¼ 900 GeV performed by the ALICE experiment at the Large Hadron Collider. Our analysis shows an increase of the Hanbury Brown-Twiss radius with increasing event multiplicity, in line with other measurements done in particle-and nuclear collisions. Conversely, the strong decrease of the radius with increasing transverse momentum, as observed at the Relativistic Heavy Ion Collider and at Tevatron, is not manifest in our data.

“…The large number of events collected by NOMAD allows the study of BEC effects in different final state configurations. In particular it is interesting to verify the observations in hadronic [26] and e + e − interactions [20] that the Goldhaber radius increases with the event charged multiplicity N ch . Fig.…”

Bose-Einstein Correlations in one and two dimensions have been studied, with high statistics, in charged current muon-neutrino interaction events collected with the NOMAD detector at CERN. In one dimension the Bose-Einstein effect has been analyzed with the Goldhaber and the Kopylov-Podgoretskii phenomenological parametrizations. The Goldhaber parametrization gives the radius of the pion emission region R G = 1.01 ± 0.05(stat) +0.09 −0.06 (sys) fm and for the chaoticity parameter the value λ = 0.40 ± 0.03(stat) +0.01 −0.06 (sys). Using the Kopylov-Podgoretskii parametrization yields R KP = 2.07 ± 0.04(stat) +0.01 −0.14 (sys) fm and λ KP = 0.29 ± 0.06(stat) +0.01 −0.04 (sys). Different parametrizations of the long-range correlations have been also studied. The two-dimensional shape of the source has been investigated in the longitudinal co-moving frame. A significant difference between the transverse and the longitudinal dimensions is observed. The high statistics of the collected sample allowed the study of the Bose-Einstein correlations as a function of rapidity, charged particle multiplicity and hadronic energy. A weak dependence of both radius and chaoticity on multiplicity and hadronic energy is found.

The experimental data on inclusive cross sections of jet, direct photon and hadron production in pp/pp and AA collisions at RHIC and Tevatron are analyzed in the framework of z-scaling. Results of analysis are compared with data obtained at ISR, SppS and Tevatron. The properties of z-presentation of experimental data are verified. Physical interpretation of the scaling function ψ(z) and variable z is discussed. The locality, self-similarity and fractality are argued to reflect the general structure of the colliding objects, interaction of their constituents and particle formation at small scales. The obtained results suggest that the z-scaling may be used as a tool for searching for new physics phenomena beyond Standard Model in hadron and nucleus collisions at high transverse momentum and high multiplicity at U70, RHIC, Tevatron and LHC.
