title: "Figure 8 left" of "Investigating $\Lambda$ baryon production in p-Pb collisions in jets and the underlying event using angular correlations"

description: The (h-$\Lambda$)/(h-$\phi$) yield ratio as a function of multiplicity in the near side, away side and underlying event for the 4-8 GeV/c trigger momentum and 1.5-2.5 GeV/c associated momentum bin. The relationship between charged particle multiplicity and event multiplicity class (by percentile) is given in Table 5 of the corresponding manuscript.
description: First measurements of hadron(h)-$\Lambda$ azimuthal angular correlations in p--Pb collisions at $\sqrt{s_{\text{NN}}}= 5.02$ TeV using the ALICE detector at the LHC are presented. These correlations are used to separate the production of associated $\Lambda$ baryons into three different kinematic regions, namely those produced in the direction of the trigger particle (near-side), those produced in the opposite direction (away-side), and those whose production is uncorrelated with the jet-axis (underlying event). The per-trigger associated $\Lambda$ yields in these regions are extracted, along with the near- and away-side azimuthal peak widths, and the results are studied as a function of associated particle $p_{\text{T}}$ and event multiplicity. Comparisons with the DPMJET event generator and previous measurements of the $\phi(1020)$ meson are also made. The final results indicate that strangeness production in the highest multiplicity p-Pb collisions is enhanced relative to low multiplicity collisions in the jet-like regions, as well as the underlying event. The production of $\Lambda$ relative to charged hadrons is also enhanced in the underlying event when compared to the jet-like regions. Additionally, the results hint that strange quark production in the away-side of the jet is modified by soft interactions with the underlying event.

description: Comparison of $p_{\rm T}$-independent branching-fraction ratio ${\rm BR}(\Omega^0_{\rm c}\rightarrow\Omega^{-}{\rm e}^{+}\nu_{\rm e})/{\rm BR}(\Omega^0_{\rm c}\rightarrow\Omega^{-}{\pi}^{+})$ between experiments and theoretical calculations.
description: The inclusive production of the charm-strange baryon $\Omega^0_{\rm c}$ is measured for the first time via its semileptonic decay into $\Omega^{-}\rm e^{+}\nu_{e}$ at midrapidity ($|y|&lt;0.8$) in proton proton (pp) collisions at the centre-of-mass energy $\sqrt{s}=13$ TeV with the ALICE detector at the LHC.

title: "Figure 2.1" of "Investigating strangeness enhancement with multiplicity in pp collisions using angular correlations"

description: Yields of $\rm K^{0}_\rm{S}$ per trigger particle per unit $\Delta\eta\Delta\varphi$ area in pp collisions at $\sqrt{s}=13$ TeV, as a function of the $\rm K^{0}_\rm{S}$ $p_\rm{T}$. Trigger particles are charged particles with $p_\rm{T}&gt;3$ GeV/c. The trigger-particle-$\rm K^{0}_\rm{S}$ correlation is integrated in the ranges $-1.2&lt;\Delta\eta&lt;1.2$ and $-\pi/2&lt;\Delta\varphi&lt;3/2\pi$.
description: A study of strange hadron production associated with hard scattering processes and with the underlying event is conducted to investigate the origin of the enhanced production of strange hadrons in small collision systems characterised by large charged-particle multiplicities. The production of the single-strange meson ${\rm K}^{0}_{\rm{S}}$ and the double-strange baryon $\Xi^{\pm}$ is measured, in each event, in the azimuthal direction of the highest-$p_{\rm T}$ particle (trigger particle), related to hard scattering processes, and in the direction transverse to it in azimuth, associated with the underlying event, in pp collisions at $\sqrt{s}=5.02$ TeV and $\sqrt{s}=13$ TeV using the ALICE detector at the LHC. The per-trigger yields of ${\rm K}^{0}_{\rm{S}}$ and $\Xi^{\pm}$ are dominated by the transverse-to-leading production (i.e., in the direction transverse to the trigger particle), whose contribution relative to the toward-leading production is observed to increase with the event charged-particle multiplicity. The transverse-to-leading and the toward-leading $\Xi^{\pm}$/${\rm K}^{0}_{\rm{S}}$ yield ratios increase with the multiplicity of charged particles, suggesting that strangeness enhancement with multiplicity is associated with both hard scattering processes and the underlying event. The relative production of $\Xi^{\pm}$ with respect to ${\rm K}^{0}_{\rm{S}}$ is higher in transverse-to-leading processes over the whole multiplicity interval covered by the measurement. The ${\rm K}^{0}_{\rm{S}}$ and $\Xi^{\pm}$ per-trigger yields and yield ratios are compared with predictions of three different phenomenological models, namely Pythia8.2 with the Monash tune, Pythia8.2 with ropes and EPOS LHC. The comparison shows that none of them can quantitatively describe either the transverse-to-leading or the toward-leading yields of ${\rm K}^{0}_{\rm{S}}$ and $\Xi^{\pm}$.
