title: "Table 4 (middle right)" of "Investigating the role of strangeness in baryon$-$antibaryon annihilation at the LHC"

description: $p-\overline{\Lambda}\oplus \Lambda-\overline{p}$ correlation function in high-multiplicity pp collisions at $\sqrt{s}=13$ TeV for the trasverse mass bin $1.44 &lt; m_T &lt; 1.65$ GeV/$c^2$.
description: Annihilation dynamics plays a fundamental role in the baryon--antibaryon ($B-\overline{B}$) interaction at low-energy and its strength and range are crucial in the assessment of possible baryon bound states.
Experimental data on annihilation cross sections are available for the $p-\overline{p}$ system but not in the low relative momentum region.
Data regarding the $B-\overline{B}$ interaction with strange degrees of freedom are extremely scarce or absent, hence the modeling of the annihilation contributions is mainly based on nucleon--antinucleon ($N-\overline{N}$) results, when available.
In this letter we present a measurement of the $p-\overline{p}$, $p-\overline{\Lambda}\oplus \Lambda-\overline{p}$ and $\Lambda-\overline{\Lambda}$ interaction using correlation functions in the relative momentum space in high-multiplicity triggered pp collisions at \onethree recorded by ALICE at the LHC.
In the $p-\overline{p}$ system the couplings to the mesonic channels in different partial waves are extracted by adopting a coupled-channel approach with recent $\chi$EFT potentials. The inclusion of these inelastic channels provides good agreement with the data, showing a significant presence of the annihilation term down to zero momentum.
Predictions obtained using the Lednick$\'y$--Lyuboshits formula and scattering parameters obtained from
heavy-ion collisions, hence mainly sensitive to elastic processes, are compared with the experimental $p-\overline{\Lambda}\oplus \Lambda-\overline{p}$ and $\Lambda-\overline{\Lambda}$ correlations. The model describes the $\Lambda-\overline{\Lambda}$ data and underestimates the $p-\overline{\Lambda}\oplus \Lambda-\overline{p}$ data in the region of momenta below 200 MeV/$c$.
The observed deviation indicates a different contribution of annihilation channels to the two systems containing strange hadrons.

title: "Table 44" 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: Near-side associated peak yield of D mesons (average of D$^{0}$, D$^{+}$, and D$^{*+}$) correlated with charged particles, as a function of the D-meson $p_{\rm T}$, for associated particle $2 &lt; p_{\rm T} &lt; 3$ GeV/$c$.

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.
