Particle dynamics on hyperboloid and unitary representation of SO(1,N) group
George Jorjadze, Wlodzimierz Piechocki
We analyze particle dynamics on dimensional one-sheet hyperboloid embedded in dimensional Minkowski space. The dynamical integrals constructed by symm…
Oscillations of Cumulant Moments - Universality of Amplitudes
M. Rybczynski, G. Wilk, Z. Wlodarczyk +2
We demonstrate on simple examples that oscillatory behaviour of moments of multiplicity distributions P(n) observed in e^+e^- annihilations, in hadronic pp collisions and in collis…
A new measurement of direct CP violation in two pion decays of the neutral kaon
The NA48 Collaboration, V. Fanti
The NA48 experiment at CERN has performed a new measurement of direct CP violation, based on data taken in 1997 by simultaneously collecting K_L and K_S decays into pi0pi0 and pi+p…
Interpretation of the nonextensitivity parameter in some applications of Tsallis statistics and Lévy distributions
G. Wilk, Z. Wlodarczyk
The nonextensitivity parameter occuring in some of the applications of Tsallis statistics (known also as index of the corresponding Lévy distribution) is shown to be given, in…
Centrality Dependence of Directed and Elliptic Flow at the SPS
NA49 Collaboration, A. M. Poskanzer, S. A. Voloshin
New data with a minimum bias trigger for 158 GeV/nucleon Pb + Pb have been analyzed. Directed and elliptic flow as a function of rapidity of the particles and centrality of the col…
Contour gauges, canonical formalism and flux algebras
L. Lukaszuk, E. Leader, A. Johansen
A broad class of contour gauges is shown to be determined by admissible contractions of the geometrical region considered and a suitable equivalence class of curves is defined. In…
