[en] Particle-emission probabilities from 100 to 1 GeV excited ¹⁹⁰Hg have been calculated within the framework of statistical models, and results indicate that the emission probabilities of large clusters, such as Zn, Gd, and Er, compete favorably with those of neutron and alpha emission. Calculations are compared to the data. The process is driven by energy released in these exothermal reactions. Some of these emitted clusters are likely to fission to various modes. The cluster-emission-fission chain continues until daughter products cool down sufficiently so that neutron emission becomes dominant. Calculations for A and X emission probabilities have also been done

[en] The two-point correlation functions are calculated from different probability functions for a given volume. It is shown that two of the five probability functions usually caused can marginally produce the systematics of the large scale clustering observed for Abell clusters

[en] We develop an explicite procedure for the evaluation of the reduced width amplitude for the emission of clusters heavier than alpha particle. (authors)

[en] The general features of high-energy collisions of elementary particles are outlined. It is argued that multiple production occurs through the production of hadronic clusters. The history and present status of the cluster concept are surveyed

[en] The internal structure of hadronic showers can be resolved in a high-granularity calorimeter. This structure is described in terms of simple components and an algorithm for reconstruction of hadronic clusters using these components is presented. Results from applying this algorithm to simulated hadronic Z-pole events in the SiD concept are discussed

[en] A brief discursive summary of the structure of events; and for particle interactions some unanswered questions are presented. (auth)

[en] We consider two scenarios of New Physics: the Large Extra Dimensions (LED), where sterile neutrinos can propagate in a (4 + d)-dimensional space-time, and the Non Standard Interactions (NSI), where the neutrino interactions with ordinary matter are parametrized at low energy in terms of effective flavour-dependent complex couplings εαβ. We study how these models have an impact on oscillation parameters in reactor and accelerator experiments.

[en] An improved version of the cluster theorem of relativistic quantum field theory with the correct exponential decay is derived by function theoretical methods

[en] The effects of the Bose-Einstein symmetry for emitted pions in the decay of clusters with isospin I=0, 1 via linear chain decay are investigated. The decay spectra are calculated of the fixed spin dual resonance model cluster into a ground state particle (''pion''). The normalized decay spectrum is obtained by summing over all final states and averaging over all initial states. (Z.J.)
