AbstractAbstract
[en] The UPSILON(1S)decays most observables (sphericity, charged multiplicity, photonic energy fraction, inclusive spectra) can be understood assuming that gluons fragments like quarks. New results from LENA use the (axis-independent) Fox-Wolfram moments for the photonic energy deposition. Continuum reactions show ''standard'' Field-Feynman fragmentation. UPSILON(1S) decays show a significant difference in the photonic energy topology. It is more isotropic than with the Field-Feynman fragmentation scheme. Gluon fragmentation into isoscalar mesons (a la Peterson and Walsh) is excluded. But if one forces the leading particle to be isoscalar, one gets good agreement

AbstractAbstract
[en] Decreasing of the cross sections of inclusive processes and planarity phenomenon at high energies are discussed on the basis of analyticity in angular variables. The problem is solved with the aid of Neyman-Pirson lemma and Truassar limitation upon differential cross sections in the region of fixed angles of particle escape

AbstractAbstract
[en] Particle production in Au+Au collisions has been measured in the PHOBOS experiment at RHIC for a range of collision energies. Three empirical observations have emerged from this dataset which require theoretical examination. First, there is clear evidence of limiting fragmentation. Namely, particle production in central Au + Au collisions, when expressed as dN/dη' (η' (triplebond) η - ybeam), becomes energy independent at high energy for a broad region of η' around η' = 0. This energy-independent region grows with energy, allowing only a limited region (if any) of longitudinal boost-invariance. Second, there is a striking similarity between particle production in e+e- and Au + Au collisions (scaled by the number of participating nucleon pairs). Both the total number of produced particles and the longitudinal distribution of produced particles are approximately the same in e+e- and in scaled Au + Au. This observation was not predicted and has not been explained. Finally, particle production has been found to scale approximately with the number of participating nucleon pairs for < Npart> > 65. This scaling occurs both for the total multiplicity and for high pT particles (3 < pT < 4.5 GeV/c)

AbstractAbstract
[en] We determine the two-loop 'time-like' Altarelli-Parisi splitting functions, appearing in the next-to-leading order Q2-evolution equations for fragmentation functions, via analytic continuation of the corresponding 'space-like' splitting functions for the evolution of parton distributions. We do this for the case of unpolarized fragmentation functions and - for the first time - also for the functions describing the fragmentation of a longitudinally polarized parton into a longitudinally polarized spin-1/2 hadron such as a Λ baryon. Our calculation is based on the method proposed and employed by Curci, Furmanski and Petronzio in the unpolarized case in which we confirm their results. (Author)
