It is demonstrated how to obtain the least biased description of a single particle spectra measured in
all multiparticle production processes by using an information theory approach (known also as MaxEnt
approach). The case of e+e- annihilation in hadrons process is
discussed in more detail as an example. Comparison between the MaxEnt approach and a simple dynamical
model based on the cascade process is presented as well.
