| Abstract | Dao et al. (1974) proposed the hypotheses that the distributions, properly normalized of 'mean scaled' variables in multiparticle production at high energies are independent of multiplicity, initial state and incident energy. The multiplicity dependence of fhe mean- scaled variables x/(x) are studied for various semi-inclusive (or exclusive) reactions in the pp annihilation around 1 GeV/c incident momentum (x=p/sub t/, mod p/sub L/ mod ) using the 81 cm CERN hydrogen bubble chamber data. It is found that the distributions are poorly described by universal functions. (6 refs). |
