title: "Table 5" of "First observation of strange baryon enhancement with effective energy in pp collisions at the LHC"

description: Self-normalised ZN energy as a function of the self-normalised charged-particle-multiplicity in pp collisions at $\sqrt{s}$ = 13 TeV in the low-ZN-energy classification (V0M+SPDClusters event classes).
description: The production of (multi-)strange hadrons is measured at midrapidity in proton-proton (pp) collisions at $\sqrt{s} = 13$ TeV as a function of the local charged-particle multiplicity in the pseudorapidity interval $|\eta|&lt;0.5$ and of the very-forward energy measured by the ALICE Zero-Degree Calorimeters (ZDC). The latter provides information on the effective energy available for particle production in the collision once subtracted from the centre-of-mass energy. The yields of $K^{0}_{S}$, $\Lambda + \overline{\Lambda}$, and $\Xi^{-} + \overline{\Xi}^{+}$ per charged-particle increase with the effective energy. In addition, this work exploits a multi-differential approach to decouple the roles of local multiplicity and effective energy in such an enhancement. The results presented in this article provide new insights into the interplay between global properties of the collision, such as the initial available energy in the event, and the locally produced final hadronic state, connected to the charged-particle multiplicity at midrapidity. Notably, a strong increase of strange baryon production with effective energy is observed for fixed charged-particle multiplicity at midrapidity. These results are discussed within the context of existing phenomenological models of hadronisation implemented in different tunes of the PYTHIA 8 event generator.

title: "Table 1" of "Investigating strangeness enhancement in jet and medium via $\phi$(1020) production in p$-$Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV"

description: Pet-trigger h--$\phi$ and h--h pair yields within the near and away-side jet peaks as a function of charged particle multiplicity in p--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV in the pseudorapidity region $|\eta|&lt;0.8$. Pairs consist of a trigger hadron in the range $4.0 &lt; p_{\mathrm{T, trig}} &lt; 8.0 \mathrm{~GeV}/c$ and an associated $\phi$(1020) (h) in the range $1.5 &lt; p_{\mathrm{T, assoc}} &lt; 2.5 \mathrm{~GeV}/c$.
description: Yields of h--$\phi$ and h--h pairs were measured in p--Pb collisions at center-of-mass energy per nucleon pair $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV in the pseudorapidity region $|\eta|&lt;0.8$, collected with the ALICE detector at the LHC. The $\phi$(1020) mesons were reconstructed from their KK decay channel (B.R. = 0.491) and correlated with a high momentum ($4.0 &lt; p_{\mathrm{T}} &lt; 8.0 \mathrm{~GeV}/c$) trigger hadron acting as a jet proxy. These angular correlations were separated into a near-side jet region, an away-side jet region, and an underlying event (UE), allowing for a comparison between jet and UE production. Di-hadron correlations were also measured to compare against. The correlations were performed in a lower ($1.5 &lt; p_{\mathrm{T}} &lt; 2.5 \mathrm{~GeV}/c$) and a higher ($2.5 &lt; p_{\mathrm{T}} &lt; 4.0 \mathrm{~GeV}/c$) associated momentum range. Jet yields for h--$\phi$ pairs in the lower associated momentum range show a hint of an increase with increasing event multiplicity. To further study $\phi$ production, the ratio of (h--$\phi$)/(h--h) pairs was measured separately in the near-side jet, away-side jet, and UE regions. This ratio shows a clear ordering for all multiplicities and both assocaited momentum ranges, with the UE ratio significantly higher than the ratio in the jets. It is also seen that the ratio in the jets at lower associated momentum shows hints of an increase with multiplicity, which is not seen in the higher associated momemtum measurement. The UE ratio shows no depdendence on charged particle multiplicity, and invites further study to search for an onset of strangeness enhancement at lower multiplicities.
