Aa. Anselm et Mg. Ryskin, THE PRODUCTION OF A NONHOMOGENEOUS CLASSICAL PION FIELD AND THE DISTRIBUTION OF THE NEUTRAL AND CHARGED PIONS, ZEITSCHRIFT FUR PHYSIK A-HADRONS AND NUCLEI, 358(3), 1997, pp. 353-355
The probability distribution dw/df as a function of the ratio f = n(0)
/n(tot) of the neutral to total multiplicities is calculated for the c
lassical pion fields quickly varying in space and time.
