Abstract
We have studied the interactions of 400-GeV/c protons with beryllium nuclei and observed hadrons produced at large transverse momenta () back to back near 90° in the proton-nucleon center-of-momentum system. When both transverse momenta exceed about 2.6 GeV/c, we observe that the probability per single hadron of observing a second high- hadron on the opposite side approximately scales in the ratio of the two transverse momenta ( scaling). Quantum-number correlations between the opposite-going high- hadrons are weak.
