| Abstract: | In pp collisions at √s = 44.7 and 62.3 GeV, where each proton fragments into at least one low-pT, high-x meson or baryon, no correlations between the particle momenta are found for ππ, πK, KK, and pπ pairs. The ππ data show a preference for the formation of electrically neutral ππ systems. The KK data show the influence of strangeness conservation. For pp and pΛ final states, the momentum dependence of the correlation ratio R can be described by the scaling variable z = (1 ? x1)(1 ? x2). Small deviations from factorization are discussed. |
