Query: System size and Multiplicity dependence of Chemical freeze-out
  parameters at the Large Hadron Collider Energies   The collision system and multiplicity dependence of chemical freeze-out
temperature ($T_{\rm ch}$) and strangeness saturation factor ($\gamma_{s}$) are
obtained by studying the particle ratios at the Large Hadron Collider (LHC)
energies. Here, we consider the new results in pp at 13 TeV, p+Pb at
$\sqrt{s_{\rm NN}}$ = 5.02 TeV, Xe+Xe at $\sqrt{s_{\rm NN}}$ = 5.44 TeV and
Pb+Pb at $\sqrt{s_{\rm NN}}$ = 5.02 TeV along with the earlier results in pp at
$\sqrt{s}$ = 7 TeV and Pb+Pb at $\sqrt{s_{\rm NN}}$ = 2.76 TeV. A statistical
thermal model is used to extract the chemical freeze-out parameters in
different multiplicity classes. To understand the particle production from
small to large collision systems two ensembles namely, canonical and grand
canonical have been considered in this study. A clear observation of
multiplicity dependence of $T_{\rm ch}$ and $\gamma_{s}$ is observed. The
values obtained in high-multiplicity pp collisions are found to be similar to
the peripheral Pb+Pb collisions. A final state midrapidity charged particle
multiplicity density of around 20-30 appears to be a threshold below which, the
chemical freeze-out temperature is lower than the kinetic freeze-out
temperature.
