charge reassigning algorithm
Opis:: Using UrQMD generated Au-Au collisions, two different methods of introducing Bose-Einstein (BE) correlations among final state particles are applied. New algorithm, which reassigns charges of produced particles but does not alter the original four-momenta, provided by an event generator, is compared to the standard weighting method. Correlation functions C2 in qinv and Bertsch-Pratt parametrizations are studied. While longitudinal radii are the same in both approaches, the transverse and invariant radii as well as the correlation strength ë are substantially overestimated in charge reassigning approach.

Opis:: The possibilities of ALICE experiment in measurements of particle correlations are estimated by computer simulations. A dedicated software has been created with the aim to study the influence of different experimental factors on the shape of correlation functions and with the intention to serve in the future for the analysis of real data. A scheme of correlation analysis is described shortly and some of the first results are presented. This analysis is being performed in the frame of ALICE "Physics Performance Report".

Opis:: The shape of Bose-Einstein (or HBT) correlation functions is determined for the case when particles are emitted from a stable source, obtained after convolutions of large number of elementary random processes. The two-particle correlation function is shown to have a stretched exponential shape, characterized by the Lévy index of stability 0 < alfa less-than or equal to 2 and the scale parameter R. The normal, Gaussian shape corresponds to a particular case, when alfa = 2 is selected. The asymmetry parameter of the stable source, beta is shown to be proportional to the angle, measured by the normalized three-particle cumulant correlations.

relativistic heavy-ion collisions
Opis:: The PHENIX experiment at the Relativistic Heavy Ion Collider has performed a survey of momentum correlations ranging from 200 MeV/c to 7 GeV/c in sNN = 200 GeV p+p, d+Au, Au+Au, and sNN = 62 GeV Au+Au collisions. The correlations are measured separately for like-sign and unlike-sign pairs. Comparisons of the properties of the near-side peak amplitude and width as a function of centrality and transverse momentum for each collision species are presented and discussed.
