A bstract The production of non-prompt D 0 mesons from beauty-hadron decays was measured at midrapidity (| y | < 0 . 5) in Pb-Pb collisions at a nucleon-nucleon center-of-mass energy of $$ \sqrt{{\textrm{s}}_{\textrm{NN}}} $$ s NN = 5 . 02 TeV …

Abstract In our Galaxy, light antinuclei composed of antiprotons and antineutrons can be produced through high-energy cosmic-ray collisions with the interstellar medium or could also originate from the annihilation of dark-matter particles that have not yet been discovered. On Earth, the only …

Abstract The multiplicity dependence of jet production in pp collisions at the centre-of-mass energy of $$\sqrt{s} = 13\ {\mathrm {TeV}}$$ s = 13 TeV is studied for the first time. Jets are reconstructed from charged particles using the anti- $$k_\mathrm {T}$$ k …

Abstract Angular correlations of heavy-flavour and charged particles in high-energy proton–proton collisions are sensitive to the production mechanisms of heavy quarks and to their fragmentation as well as hadronisation processes. The measurement of the azimuthal-correlation function of prompt D mesons with charged …

The production yield and angular anisotropy of prompt Ds+ mesons were measured as a function of transverse momentum (pT) in Pb–Pb collisions at a centre-of-mass energy per nucleon pair sNN=5.02TeV collected with the ALICE detector at the LHC. Ds+ mesons and their …

The prompt production of the charm baryon ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}$ and the ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}/{D}^{0}$ production ratios were measured at midrapidity with the ALICE detector in $pp$ and $p$-Pb collisions at $\sqrt{{s}_{\mathrm{NN}}}=5.02\text{ }\text{ }\mathrm{TeV}$. These new measurements show a clear decrease of the ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}/{D}^{0}$ ratio with …

The first measurements of the scattering parameters of $\mathrm{\ensuremath{\Lambda}}K$ pairs in all three charge combinations ($\mathrm{\ensuremath{\Lambda}}{K}^{+}, \mathrm{\ensuremath{\Lambda}}{K}^{\ensuremath{-}}$, and $\mathrm{\ensuremath{\Lambda}}{K}_{S}^{0}$) are presented. The results are achieved through a femtoscopic analysis of $\mathrm{\ensuremath{\Lambda}}K$ correlations in Pb-Pb collisions at $\sqrt{{s}_{NN}}=2.76$ TeV recorded by ALICE at …
