The production yield of the $\mathrm{\ensuremath{\Lambda}}(1520)$ baryon resonance is measured at midrapidity in Pb-Pb collisions at $\sqrt{{s}_{\mathit{NN}}}$ = 2.76 TeV with the ALICE detector at the Large Hadron Collider (LHC). The measurement is performed in the $\mathrm{\ensuremath{\Lambda}}(1520)\ensuremath{\rightarrow}\mathrm{p}{\mathrm{K}}^{\ensuremath{-}}$ (and charge conjugate) hadronic decay …

We present the first measurements of femtoscopic correlations between the K S 0 and K ± particles in pp collisions at s = 7 TeV measured by the ALICE experiment. The observed femtoscopic correlations are consistent with final-state interactions proceeding solely via …

Abstract Transverse-momentum (p T) differential yields of electrons from semileptonic heavy-flavour hadron decays have been measured in the most central (0–10%) and in semi-central (20–40%) Pb–Pb collisions at $$ \sqrt{s_{\mathrm{NN}}}=2.76 $$ s N N = 2.76 TeV. The corresponding production cross section …

In two-particle angular correlation measurements, jets give rise to a near-side peak, formed by particles associated to a higher-${p}_{\mathrm{T}}$ trigger particle. Measurements of these correlations as a function of pseudorapidity ($\mathrm{\ensuremath{\Delta}}\ensuremath{\eta}$) and azimuthal ($\mathrm{\ensuremath{\Delta}}\ensuremath{\varphi}$) differences are used to extract the centrality and …
