Production properties of low-mass systems in pp collisions at 102 GeV/c

We examine in detail the properties of low-mass systems produced in the inclusive reaction p + p → p + anything at 102 GeV/c. We find that the internal characteristics of these low-mass nucleon-multipion systems (the “anything”), at fixed values of mass (M), are similar to those found for produced hadrons in high-energy collisions at fixed incident hadron energies $\text{(}\text{s}\text{)}$. The resemblance between the properties of the M² system and the characteristics of πp collisions at s = M² is particularly striking.
