Abstract Results on two-particle η φ correlations in
inelastic p + p interactions at 20, 31, 40, 80, and 158 GeV/c
are presented. The measurements were performed using the
large acceptance NA61/SHINE hadron spectrometer at the
CERN Super Proton Synchrotron. The data show structures
which can be attributed mainly to effects of resonance decays,
momentum conservation, and quantum statistics. The results
are compared with the Epos and UrQMD models.
1 Introduction and motivation
This paper presents experimental results on two-particle
correlations in pseudorapidity and azimuthal angle of charged
particles produced in inelastic p + p interactions at 20, 31, 40,
80, and 158 GeV/c. The measurements were performed by
the
multi-purpose NA61/SHINE [1,2] experiment at the CERN
Super Proton Synchrotron (SPS). They are part of the strong
interactions programme devoted to the study of the
properties of th (...truncated)
