      Abstract:
      
      ​The NA61/SHINE experiment at the CERN SPS has recently extended its
      program for the energy scan with Pb ions. In the past, the NA49
      experiment, which preceded NA61/SHINE, also recorded data for
      Pb-Pb collisions at different energies. Together, the two experiments
      cover a wide range of beam energies provided by the CERN SPS in the range 13 - 150 A GeV/c. Analysis of the new NA61/SHINE data and reanalysis of the existing NA49 data
      using modern measurement techniques allow for a new comprehensive
      systematic study of collective flow relative to the spectator plane. The measurements at the lowest energy available at the SPS are also
      relevant for the preparation of the Compressed Baryonic Matter (CBM)
      heavy-ion​ experiment​ at​ the​ future​ FAIR​ facility​ in​ Darmstadt.
      
      We will present new NA61/SHINE results on directed and elliptic flow
      measurement in Pb-Pb collisions at 13 and 30A GeV/c relative to the
      spectator plane determined with the Projectile Spectator Detector. Also
      a new analysis of 40​A GeV data collected by the NA49 experiment using
      forward spectator calorimeters (VETO and RCAL) will be shown. The flow
      coefficients are reported as a function of rapidity and transverse
      momentum in different classes of collision centrality. The new results
      are compared with existing results from the previous NA49 analysis and
      the STAR experiment at RHIC.

      Talk (invitation for NA61/SHINE): Future physics program and prospectives for the NA61/SHINE large acceptance particle spectrometer at the CERN SPS 20m
      Speaker: Andrey Seryakov (St Petersburg State University (RU))

      Future physics program and prospectives for the NA61/SHINE large acceptance particle spectrometer at the CERN SPS.

      The NA61/SHINE collaboration accomplished the originally proposed program
      of data taking at the end of 2018. The new 2020+ research plan will be presented. 
      It includes:
        - the new upgraded experimental setup;
        - the open-charm production in Pb+Pb collisions which has never been measured at such low energies;
        - improved hadron production measurements for current and future Long-Baseline Neutrino experiments;
        - nuclei fragmentation studies for understanding of the propagation of cosmic rays in the Galaxy.
       The ideas for new studies after the CERN LS3 will be discussed.
