摘要：
We have measured two-particle quantum-number correlations in 400-GeV/c proton-nucleus collisions. A double-arm spectrometer was used to detect two charged particles produced near rapidity yc.m.=-0.4 in the proton-nucleon center-of-mass system. In proton-beryllium collisions we observe positive pp̄ and K+K- correlations which are independent of the transverse momenta of the particles over the range 1<p<1.8 GeV/c. These correlations are weaker in proton-lead interactions. © 1979 The American Physical Society.
