The entropy properties are analyzed by Ma's coincidence method in π+p and K+p collisions of the NA22 experiment at 250 GeV/c incident momentum. By using the Rényi entropies, we test the scaling law and additivity properties in rapidity space. The behavior of the Rényi entropies as a function of the average number of particles is investigated. The results are compared with those from the PYTHIA Monte Carlo event generator.
We show that Sigma(+) hyperons produced by 800 GeV/c protons on targets of Be and Cu have significant polarizations (15-20%). These polarizations persist at values of p(t)approximate to2 GeV/c and a wide range of x(F). The polarizations from the Cu target are consistently less than from Be. The average ratio of the Sigma(+) polarization from Cu to that from Be is 0.68+/-0.08.
