Query: Exploring the string shoving model in PYTHIA8 for collective behaviors
  in $pp$ collisions   Two-particle correlations have been used to study property of a produced
medium called Quark-Gluon Plasma (QGP) in relativistic heavy-ion collisions,
and a long-range correlation among produced particles has been considered as a
strong evidence of strongly interacting QGP. Strikingly, clear long-range
correlations have been also observed in small collision systems like $pp$ and
$p$+$A$ at a wide range of collision energies. A model introducing a repulsive
force between flux tubes called string shoving can qualitatively describe the
long-range near-side correlations in high multiplicity $pp$ collisions. This
model implemented in the PYTHIA Monte Carlo event generator allows us to
perform detailed study. In this work, a full data analysis to calculate
associated yields and flow coefficients is performed with PYTHIA events, and
the results are compared with experimental results. We find that the string
shoving model overestimates long-range near-side correlations particularly in
low multiplicity events. We also introduce a method to subtract such
overestimated correlations in low multiplicity to have a more relevant
comparison with the data.
