Multiplicity distributions in hadron-hadron collisions based on the universality ansatz

Description: Recent experiments on small-p/sub T/ hadron production in pp collisions have shed new light on the apparent violation of the universality ansatz that the multiplicity dispersion in hadron-hadron collisions is much larger than that in e/sup +/e/sup -/ collisions. We present a model based on the universality ansatz, among other things. This model reproduces qualitatively the hadron multiplicity distributions in pp collisions over a wide range of energies. Within our framework, this essentially re… more

A multi-threshold sampling method for TOF PET signal processing

Description: As an approach to realizing all-digital data acquisition for positron emission tomography (PET), we have previously proposed and studied a multithreshold sampling method to generate samples of a PET event waveform with respect to a few user-defined amplitudes. In this sampling scheme, one can extract both the energy and timing information for an event. In this paper, we report our prototype implementation of this sampling method and the performance results obtained with this prototype. The prot… more
