title: "Figure 4" of "Measurement of the production cross section of prompt $\Xi^0_{\rm c}$ baryons in p$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}~=~5.02$ TeV"

description: $\Xi_\mathrm{c}^0~R_\mathrm{pPb}$ as a function of $p_\mathrm{T}$ in p–Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV.
description: CERN-LHC. ALICE. The transverse momentum ($p_\mathrm{T}$) differential production cross section of the promptly produced charm-strange baryon $\Xi_\mathrm{c}^0$ (and its charge conjugate $\overline{\Xi_\mathrm{c}^0}$) is measured at midrapidity via its hadronic decay into ${\pi^{+}}\Xi^{-}$ in p$-$Pb collisions at a centre-of-mass energy per nucleon$-$nucleon collision $\sqrt{s_\mathrm{NN}}= 5.02$ TeV with the ALICE detector at the LHC. The $\Xi_\mathrm{c}^0$ nuclear modification factor ($R_\mathrm{pPb}$), calculated from the cross sections in pp and p$-$Pb collisions, is presented and compared with the $R_\mathrm{pPb}$ of $\mathrm{\Lambda_c^+}$ baryons. The ratios between the $p_\mathrm{T}$-differential production cross section of $\Xi_\mathrm{c}^0$ baryons and those of $\mathrm{D^0}$ mesons and $\mathrm{\Lambda_c^+}$ baryons are also reported and compared with results at forward and backward rapidity from the LHCb Collaboration. The measurements of the production cross section of prompt $\Xi^0_\mathrm{c}$ baryons are compared with a model based on perturbative QCD calculations of charm-quark production cross sections, which includes only cold nuclear matter effects in p$-$Pb collisions, and underestimates the measurement by a factor of about 50. This discrepancy is reduced when the data is compared with a model that includes string formation beyond leading-colour approximation or in which hadronisation is implemented via quark coalescence. The $p_\mathrm{T}$-integrated cross section of prompt $\Xi^0_\mathrm{c}$-baryon production at midrapidity extrapolated down to $p_\mathrm{T}$ = 0 is also reported. These measurements offer insights and constraints for theoretical calculations of the hadronisation process. Additionally, they provide inputs for the calculation of the charm production cross section in p$-$Pb collisions at midrapidity.

title: "Table 1" of "Exclusive four pion photoproduction in ultraperipheral Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV"

description: Corrected invariant mass spectrum for the coherent four pion photoproduction
description: The intense photon fluxes from relativistic nuclei provide an opportunity to study photonuclear interactions in ultraperipheral collisions. The measurement of coherently photoproduced \fourpi~final states in ultraperipheral $\rm{Pb\textendash Pb}$ collisions at \fivenn~is presented for the first time. The cross section, d$\sigma$/d$y$, times the branching ratio ($\rho\rightarrow \pi^+ \pi^+ \pi^- \pi^-$) is found to be $47.8\pm2.3~\rm{\rm{(stat.)}}\pm7.7~\rm{\rm{(syst.)}}$~mb in the rapidity interval $|y| &lt; 0.5$. The invariant mass distribution is best described by the fit assuming two excited resonances, $\rho(1450)$ and $\rho(1700)$, and the interference term between them. The values of the masses ($m$) and widths ($\Gamma$) of the resonances extracted from the fit are $m_{1}=1385\pm14~\rm{(stat.)}\pm3~\rm{(syst.)}$~\MeVmass, $\Gamma_{1}=431\pm36~\rm{(stat.)}\pm82~\rm{(syst.)}$~\MeVmass, $m_{2}=1663\pm13~\rm{(stat.)}\pm22~\rm{(syst.)}$~\MeVmass~and $\Gamma_{2}=357~\pm31~\rm{(stat.)}\pm49~\rm{(syst.)}$ \MeVmass, respectively. The measured cross sections times the branching ratios are compared to recent theoretical predictions.

title: "Table 1" 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 standalone classification (V0M 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.
