The method of removing the leading protons in the study of high-energy pp reactions, compared with the standard analysis

The method of removing the leading protons in order to study the properties of multiparticle systems produced in pp interactions is compared, in a direct way, with the standard method. The experimental results show that the remarkable agreement between pp interactions and e+e- annihilations, found by removing the leading protons, is lost if the standard analysis is adopted. This shows the validity and the relevance of our method of subtracting the leading-proton effects in order to understand the properties of multiparticle systems produced in strong interactions. The experiment has been performed using two values of the pp c.m. energy, (√s)sub(pp) = 30 and 62 GeV. (author)
