We measured the cross sections of hadron pair production (π, K, p) with symmetric momenta produced back-to-back in the c.m.s. in pp collisions in the range 0.45 ⩽ P T ⩽ 1.99 GeV/ c . Particle correlations showing dependence on quantum numbers and transverse momentum are presented. The data are discussed in the framework of parton models.

Correlations Between High Momentum Secondaries in $p p$ Collisions at $\sqrt{s}=44$.7-{GeV} and 62.3-{GeV}

In pp collisions at √ s = 44.7 and 62.3 GeV, where each proton fragments into at least one low- p T, high- x meson or baryon, no correlations between the particle momenta are found for ππ , π K, KK, and p π 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 − x 1 )(1 − x 2 ). Small deviations from factorization are discussed.
