| Summary: | An established phenomenology and theoretical interpretation of $p$-$p$
collision data at lower collision energies should provide a reference for
$p$-$p$ and other collision systems at higher energies, against which claims of
novel physics may be tested. The description of $p$-$p$ collisions at the
relativistic heavy ion collider (RHIC) has remained incomplete even as claims
for collectivity and other novelties in data from smaller systems at the large
hadron collider (LHC) have emerged recently. In this study we report the
charge-multiplicity dependence of two-dimensional (2D) angular correlations and
of single-particle (SP) densities on transverse rapidity $y_t$ and
pseudorapidity $\eta$ from 200 GeV $p$-$p$ collisions. We define a
comprehensive and self-consistent two-component (soft + hard) model (TCM) for
hadron production and report a significant $p$-$p$ nonjet (NJ) quadrupole
component as a third (angular-correlation) component. Our results have
implications for $p$-$p$ centrality, the underlying event (UE), collectivity in
small systems and the existence of flows in high-energy nuclear collisions. |
