Query: Power Law in Hadron Production   In high energy p+p(bar) interactions the mean multiplicity and transverse
mass spectra of neutral mesons from eta to Upsilon (m = 0.5 - 10 GeV/c^2) and
the transverse mass spectra of pions (m_T > 1 GeV/c^2) reveal a remarkable
behaviour: they follow, over more than 10 orders of magnitude, the power-law
function:The parameters C and P are energy dependent, but similar for all
mesons produced at the same collision energy. This scaling resembles that
expected in the statistical description of hadron production: the parameter P
plays the role of a temperature and the normalisation constant C is analogous
to the system volume. The fundamental difference is, however, in the form of
the distribution function. In order to reproduce the experimental results and
preserve the basic structure of the statistical approach the Boltzmann factor
e^(-E/T) appearing in standard statistical mechanics has to be substituted by a
power-law factor (E/Lambda)^(-P).
