title: "Figure 2 bottom center subfigure" of "Kaon-proton strong interaction at low relative momentum via femtoscopy in Pb-Pb collisions at the LHC"

description: K p (same charge) correlation function for centrality 30-40% from Pb-Pb collisions at 5020 GeV
description: CERN-LHC. In quantum scattering processes between two particles, aspects characterizing the strong and Coulomb forces can be observed in kinematic distributions of the particle pairs. The sensitivity to the interaction potential reaches a maximum at low relative momentum and vanishing distance between the two particles. Ultrarelativistic heavy-ion collisions at the LHC provide an abundant source of many hadron species and can be employed as a measurement method of scattering parameters that is complementary to scattering experiments. This study confirms that momentum correlations of particles produced in Pb--Pb collisions at the LHC provide an accurate measurement of kaon--proton scattering parameters at low relative momentum, allowing precise access to the K- p --&gt; K- p process. This work also validates the femtoscopic measurement in ultrarelativistic heavy-ion collisions as an alternative to scattering experiments and a complementary tool to the study of exotic atoms with comparable precision. In this work, the first femtoscopic measurement of momentum correlations of K- p (K+ ap) and $\K+ p (k- ap) pairs in Pb--Pb collisions at centre-of-mass energy per nucleon pair of Sqrt(s_NN)=5.02~TeV registered by the ALICE experiment is reported. The components of the K- p complex scattering length are extracted and found to be Re f_0=-0.91 +/- ~{0.03}(stat)^{+0.17}_{-0.03}(syst) and Im f_0 = 0.92+/-~{0.05}(stat)^{+0.12}_{-0.33}(syst). The results are compared with chiral effective field theory predictions as well as with existing data from dedicated scattering and exotic kaonic atom experiments.

title: "Table 1" of "Investigating charm production and fragmentation via azimuthal correlations of prompt D mesons with charged particles in pp collisions at $\sqrt{s} = 13$ TeV"

description: Comparison of the azimuthal-correlation distributions of D mesons (average of D$^{0}$, D$^{+}$, and D$^{*+}$) with $3 &lt; p_{\rm T} &lt; 5$ GeV/$c$ and charged particles with $0.3 &lt; p_{\rm T} &lt; 1$ GeV/$c$, in pp collisions at $\sqrt{s} = $5, 7, and 13 TeV, after baseline subtraction. Rapidity range for the D mesons is $|y^{\rm D}_{\rm cms}| &lt; 0.5$. Correlations are integrated for $|\Delta\eta|=|\eta_{\rm ch}-\eta_{\rm D}| &lt; 1$. The azimuthal-correlation distributions are reported in the range $0 &lt; \Delta\varphi &lt; \pi$.
description: The measurement of the azimuthal-correlation function of prompt D mesons with charged particles in pp collisions at a centre-of-mass energy of $\sqrt{s} =$ 13 TeV with the ALICE detector is reported, considering D$^{0}$, D$^{+}$, and D$^{*+}$ mesons in the transverse-momentum interval $3 &lt; p_{\mathrm{T}} &lt; 36$ GeV/$c$ at midrapidity ($|y| &lt; 0.5$), and charged particles with $p_{\mathrm{T}} &gt; 0.3$ GeV/$c$ and pseudorapidity $|\eta| &lt; 0.8$. This measurement has an improved precision and provides an extended transverse-momentum coverage compared to previous ALICE measurements at lower energies. The study is also performed as a function of the charged-particle multiplicity, showing no modifications of the correlation function with multiplicity within uncertainties. The properties and the transverse-momentum evolution of the near- and away-side correlation peaks are studied and compared with predictions from various Monte Carlo event generators. The obtained results can provide constraints on the generators. Among those considered, PYTHIA8 and POWHEG+PYTHIA6 provide the best description of the measured observables.
