title: "Figure 4 (lower panel)" of "Measurement of prompt ${ D_{s}^{+}}$ production in pp and PbPb collisions at $\sqrt{s_{_{\text{NN}}}}$ = 5.02 TeV"

description: The ratio between $p_T$-differential cross section of $D^+_s$ in pp collisions and $p_T$-differential corrected yield of $D^+_s$ mesons scaled by T$_\text{AA}$ in PbPb collisions over PYTHIA8 are shown.
description: The transverse momentum $(p_T)$ spectra of prompt D$^+_S$ mesons and charge conjugates are measured in pp and PbPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair using the CMS detector at the LHC. The measurement is performed through the $\text{D}^+_S \rightarrow \phi\pi^+\rightarrow \text{K}^+ \text{K}^-\pi^+$ decay channels with the D$^+_S$ rapidity range $|y|&lt;1.0$. The production in the $p_T$ range from 2 (6) GeV/c to 40 GeV/c in pp (PbPb) collisions is measured. Suppression of the D$^+_S$ nuclear modification factor (RAA) in PbPb collisions suggests a strong interaction between charm quarks and the quark-gluon plasma. The double ratio of prompt D$^+_S$ to prompt D$^0$ production in pp and PbPb is consistent with a PHSD model calculation and consistent with unity, which indicates that strange charm meson enhancement in PbPb collisions is not significant in the measured D$^+_S$ $p_T$ interval

We present the first measurements of femtoscopic correlations between the K$^0_{\rm S}$ and K$^{\rm \pm}$ particles in pp collisions at $\sqrt{s}=7$ TeV measured by the ALICE experiment. The observed femtoscopic correlations are consistent with final-state interactions proceeding solely via the $a_0(980)$ resonance. The extracted kaon source radius and correlation strength parameters for K$^0_{\rm S}$K$^{\rm -}$ are found to be equal within the experimental uncertainties to those for K$^0_{\rm S}$K$^{\rm +}$. Results of the present study are compared with those from identical-kaon femtoscopic studies also performed with pp collisions at $\sqrt{s}=7$ TeV by ALICE and with a K$^0_{\rm S}$K$^{\rm \pm}$ measurement in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV. Combined with the Pb-Pb results, our pp analysis is found to be compatible with the interpretation of the $a_0(980)$ having a tetraquark structure instead of that of a diquark.
