The first evidence of spin alignment of vector mesons (K^{*0} and ϕ) in heavy-ion collisions at the Large Hadron Collider (LHC) is reported. The spin density matrix element ρ_{00} is measured at midrapidity (|y|<0.5) in Pb-Pb collisions at a center-of-mass energy (sqrt[s_{NN}]) …

The quark gluon plasma produced in ultrarelativistic heavy-ion collisions at the Large Hadron Collider (LHC) can be studied by measuring the modifications of jets formed by hard scattered partons which interact with the medium. We studied these modifications via angular correlations of …

The jet radial structure and particle transverse momentum ( p T ) composition within jets are presented in centrality-selected Pb–Pb collisions at s NN = 2.76 TeV. Track-based jets, which are also called charged jets, were reconstructed with a resolution parameter of …

The ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high-transverse momentum trigger hadron in p–Pb collisions at s NN = 5.02 TeV. Jets are reconstructed from charged-particle tracks using the anti- k T algorithm with resolution …

For the first time the ALICE Collaboration has measured $D$-meson production down to zero transverse momentum at midrapidity in proton-proton collisions at the CERN Large Hadron Collider. This provides an important constraint on perturbative QCD calculations and the low-$x$ parton distribution functions. …

In high-energy heavy-ion collisions, the correlations between the emitted particles can be used as a probe to gain insight into the charge creation mechanisms. In this Letter, we report the first results of such studies using the electric charge balance function in …
