PWG2. Physics analysis topics

  • Light flavor hadron spectra, yields, and ratios

    Energy, system size and centrality dependence of the production of charged hadrons (pions, kaons, (anti)protons). Extraction of transverse momentum spectra, rapidity distributions, mean multiplicities, and particle ratios. Nuclear modification factor, antiparticle/particle ratio, radial flow, phase diagram mapping.

  • Strangeness (hyperons and hypernuclei)

    Analysis of strange hyperons (Lambda, Ksi, Omega) and their antiparticles: spectra, yields, antiparticle/particle ratio, nuclear modification factor, azimuthal anisotropy (together with PWG3). (Anti)Lambda polarization.
    Reconstruction of single and double hypernuclei: spectra, rapidity density, and lifetime.

  • Resonances

  • Light nuclei

    Production of nucleon clusters (d, t, He3, He4) in various reactions
    (from p+p to Au+Au): spectra, yields, coalescence coefficients.
