Angular distribution of shower particles produced in the collisions of 30--400-GeV protons with emulsion nuclei
For 3987 accelerator-produced jets of 30--400-GeV protons in nuclear emulsion, 's are individually calculated for each jet, where eta(theta) is a kinematic parameter introduced by us in 1967 in order to approximate the rapidity eta = arctanh(..beta.. costheta). Then by taking further averages by dividing the samples into groupings of the laboratory-system (LS) energy E/sub p/ of the primary proton ( = m/sub p/cosheta/sub p/), the number N/sub h/ of heavy prongs with LS velocity ..beta..<0.7, and the number n/sub s/ of charged shower particles with LS velocity ..beta..> or approx. =0.7, the averages dlangleeta(theta)drangle are obtained. By use of the Koba-Nielsen-Olesen scaling variable xi = n/sub s//, we find good fits of the form dlangleeta(theta)drangle-eta/sub p//2 = A'+B'/xi, where A' and B' do not have any dependence on eta/sub p/ (i.e., on E/sub p/). The significance of our findings is discussed.
