They are used for investigating properties of quark-hadron matters in heavy-ion collisions, for finding the origin of nucleon spin in polarized lepton-nucleon and nucleon-nucleon reactions, and possibly for finding exotic hadrons. In describing the hadron-production cross sections in high-energy reactions, fragmentation functions are essential quantities. A fragmentation function indicates the p...

Rubinstein and Helfand, and later Everaers et al. introduced a concept to extract primitive paths for dense polymeric melts made of linear chains (a multiple disconnected multibead ‘path’), where each primitive path is defined as a path connecting the (space-fixed) ends of a polymer under the constraint of non-interpenetration (exclude...

For hot compound nuclei of temperature ≈1-5 MeV one expects that a chain of particles (neutrons, protons, alphas...) will be evaporated with a variety of time intervals of ≈10^(-22)-10^(-20)s. The determination ofthese emission times is a major challenge for nuclear physicists. Such time intervals are too short to measure directly, but they do lead to final-state interactions between ...
