      Particle production properties at SPS energy range - recent results from NA61/SHINE experiment 20m

      Particle production properties at SPS energy range - recent results from NA61/SHINE experiment.

      Szymon Pulawski for the NA61/SHINE Collaboration

      The research programme of the NA61 collaboration covers a wide range of hadronic physics in the CERN SPS energy range. It encompasses measurements of hadron-hadron, hadron-nucleus as well as nucleus-nucleus collisions. The latter are analyzed to better understand the properties of hot and dense nuclear matter. In this contribution recent results on particle production in proton-proton, Be+Be, Ar+Sc interactions at beam energies of 19/20A, 30/31A, 40A, 75/80A and 150/158A GeV/c will be presented as well synergies with future NICA program will be emphasised.

      Fluctuations and correlations study at NA61/SHINE

      Daria Prokhorova for the NA61/SHINE Collaboration

      Strong interactions program of NA61/SHINE, the fixed-target experiment at CERN SPS, focuses on the search for the critical point of strongly interacting matter. The strategy of the Collaboration is to perform a comprehensive two dimensional scan of the phase diagram $\mu_{B} – T$ by changing the collision energy and the system size. In this scenario, if the system freeze-out occurs in the vicinity of the possible critical point, then the region of the enhanced fluctuations is expected to be observed in the final fluctuation measures. 

      The talk will review the ongoing NA61/SHINE analysis on multiplicity and transverse momentum fluctuations in terms of intensive and strongly intensive quantities. Furthermore, their pseudorapidity dependence, which corresponds to the additional scan in the baryon chemical potential $\mu_{B}$ at the freeze-out stage, will be presented among with the study of the higher moments of multiplicity distributions. Eventually, the talk sheds light on the approaches for the results corrections and possible obstacles in the analysis.

      Physics motivations and plans for open charm 20m

      NA61/SHINE detector upgrade 20m
      Speaker: Dariusz Tefelski (Warsaw University of Technology (PL))

      The NA61/SHINE detector, at the CERN SPS, is undergoing a major upgrade during the LHC Long Shutdown 2 period (2019-2021). The upgrade is essential to fulfil the requirements of new open charm measurement program. It is necessary to stress that this new physics goal can be achieve only when the readout rate will be increase by a factor 10 and the resolution of the secondary vertex in the high multiplicity tracks environment of Pb-Pb events will be improved. The following elements of the experiment are parts of the upgrade: Time Projection Chambers (TPC), Vertex Detector (VD), Beam Position Detectors (BPD), Particle Spectator Detector (PSD) and Time of Flight detectors (TOF). On top of the detectors, new Trigger and Data Acquisition (TDAQ) system is being developed. In the proposed talk the progress on design and development of new detectors and TDAQ system for NA61/SHINE experiment will be presented.
