title: "Average alpha+antialpha over proton ratio" of "Measurement of (anti)alpha production in central Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV"

description: Average alpha and antialpha over proton ratio in Pb-Pb collisions as a function of the charged particle multiplicity density at mid-rapidity
description: In this letter, measurements of (anti)alpha production in central (0-10%) Pb--Pb collisions at a center-of-mass energy per nucleon--nucleon pair of $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV are presented, including the first measurement of an antialpha transverse-momentum spectrum. Owing to its large mass, (anti)alpha production yields and transverse-momentum spectra are of particular interest because they provide a stringent test of particle production models. The averaged antialpha and alpha spectrum is included into a common blast-wave fit with lighter particles, indicating that the (anti)alpha also participates in the collective expansion of the medium created in the collision. A blast-wave fit including only protons, (anti)alpha, and other light nuclei results in a similar flow velocity as the fit that includes all particles. A similar flow velocity, but a significantly larger kinetic freeze-out temperature is obtained when only protons and light nuclei are included in the fit. The coalescence parameter $B_4$ is well described by calculations from a statistical hadronization model but significantly underestimated by calculations assuming nucleus formation via coalescence of nucleons. Similarly, the (anti)alpha-to-proton ratio is well described by the statistical hadronization model. On the other hand, coalescence calculations including approaches with different implementations of the (anti)alpha substructure tend to underestimate the data.

title: "Table 4a" of "Common femtoscopic hadron-emission source in pp collisions at the LHC"

description: K$^+$p (K$^+$p $\oplus$ K$^-\overline{\mathrm p}$) correlation function in HM pp collisions at $\sqrt{s_{\mathrm {NN}}}=13 $ TeV (1.2&lt;$m_T$&lt;1.4 GeV/$c^{2}$).
description: The femtoscopic study of pairs of identical pions is particularly suited to investigate the effective source function of particle emission, due to the resulting Bose--Einstein correlation signal. In small collision systems at the LHC, pp in particular, the majority of the pions are produced in resonance decays, which significantly affect the profile and size of the source. In this work, we explicitly model this effect in order to extract the primordial source in pp collisions at $\sqrt{s}~=~13~$TeV from charged $\pi$$-$$\pi$ correlations measured by ALICE. We demonstrate that the assumption of a Gaussian primordial source is compatible with the data and that the effective source, resulting from modifications due to resonances, is approximately exponential, as found in previous measurements at the LHC. The universality of hadron emission in pp collisions is further investigated by applying the same methodology to characterize the primordial source of K$-$p pairs. The size of the primordial source is evaluated as a function of the transverse mass ($m_{\mathrm{T}}$) of the pairs, leading to the observation of a common scaling for both $\pi$$-$$\pi$ and K$-$p, suggesting a collective effect. Further, the present results are compatible with the $m_{\mathrm{T}}$ scaling of the $\mathrm{p\mbox{-}p}$ and p$-\Lambda$ primordial source measured by ALICE in high multiplicity pp collisions, providing compelling evidence for the presence of a common emission source for all hadrons in small collision systems at the LHC. This will allow the determination of the source function for any hadron--hadron pairs with high precision, granting access to the properties of the possible final-state interaction among pairs of less abundantly produced hadrons, such as strange or charmed particles.
