  A model describing the coincidental timing of scintillating fibers is
developed. Fiber geometry, the rate of scintillation decay together with the
mean number, spatial dispersion and attenuation of emitted photons is
considered. For a specific selection of probability distributions and
parameters involved, the entire coincidental timing distributions,
corresponding FWHM values and the photon detection efficiencies are extracted.
The significance of the number of photons from the scintillation process is
specially emphasized. Additionally, the model is extended to include a
triggering feature, experimentally realized by coupling fibers to any photon
resolving device. Finally, the measurements of a coincidental timing
distribution were performed, with an excellent agreement found between the
experimental and predicted theoretical results.
