ALICE PHOS Upgrade TRD

Performance plots

  • Improvement of photon purity with improved time resolution

Performance studies of upgraded PHOS measurements in Run4

Direct photon measurements

  • direct gamma spectrum (ALICE-PUBLIC-2019-001)
  • direct gamma flow (ALICE-PUBLIC-2019-001) + possibility to study higher harmonics etc
  • gamma-gamma correlations (require excellent time resolution)
  • gamma-hadron fluctuations
  • direct gamma-hadron correlations

Pi0 and eta meson measurements

  • pi0 and eta at very high pT (require enlarged dynamic range)
  • pi0 and eta multi-differential measurements (multiplicity dependence, something more?)
  • pi0/eta ratio measurements

Strangeness measurements

  • eta' meson measurements
  • strange baryon decays with gamma

Other measurements

  • anti-neutron measurement (require excellent time resolution)

List of institutes involved

  • NRC KI
  • NRC KI - IHEP
  • VNIIEF

What about Japan, China, Czech, Norway etc?
