Abstract
A generalized Glauber-Lachs formula for Bose particle (i.e., unpolarized photon and charged pion) distributions is obtained. It contains a parameter of the number of cells or ensembles (k≥2) in addition to a ratio of the average multiplicity of Bosons coherently produced and ones incoherently produced (γ=≪nc>/≪nin>). It holds an analytic KNO scaling function. Comparisons of these formulae with data in pp collision at 200 GeV/c and at pp collider at √s=540 GeV are made. There are quantitatively good agreements among theoretical values and data.
