We present the observation of the antimatter $^{4}He$ nucleus, the heaviest observed antinucleus. The identification and measurement of anti-$^{4}He$ relies on the mean energy loss per unit track length, the time of flight of particles, and their curvature in the magnetic field of the STAR detector. Another essential detector capability was the High Level online tracking Trigger (HLT), which...

The particle identification capabilities of the ALICE experiment are unique among the four major LHC experiments. The working principles, the strategies for signal extraction, and excellent performance of the central barrel detectors in a high-multiplicity environment will be presented. The particle identification of the Inner Tracking System (ITS) and the Time Projection Chamber (TPC) are...

The ALICE experiment features several particle
identification systems, which allow us to measure spectra in a broad range of transverse momentum $p_{\mathrm{t}}$ from 100 MeV/c up to a few GeV/c.
New results on identified charged particle $p_{\mathrm{t}}$ spectra measured in proton-proton collisions at $\sqrt{s}=7$ TeV will be presented.
They will be compared to results obtained at 900...

In nucleus-nucleus collisions we distinguish early hadro-chemical freeze-out, fixing hadronic concentrations, and final kinetic freeze-out to spectral and flow features, occuring at the end of the hadronic "cascade" phase. This view has been adopted in all recent analysis of hadron production rates, which are well described in the grand canonical statistical equilibrium model. The derived...

The inclusive production of $\pi^0$ and $\eta$ mesons is measured at mid-rapidity in pp collisions over a wide transverse momentum ($p_T$) range with the ALICE experiment at $\sqrt{s}$=900GeV, 2.76~TeV and 7~TeV. The mesons are measured via two different techniques: with the calorimeters (PHOS and EMCAL) and via photon conversions reconstructed in the Central Tracking System.
A systematic...

The study of resonances production in pp collisions contributes to the proper tuning of the QCD-inspired particle production models and to the better understanding of the underlying event, while in PbPb collisions resonances are good probes to estimate the collective properties of the fireball, and in particular its lifetime.
Strange resonances can also contribute to the historical topic of...
