      Introduction 10m

      The main priorities of the group are to complete analyses (and papers!) on: (1) Diffractive cross sections (Run 2), (2) Central Exclusive Production (CEP) resonances (Run 1 and 2), and (3) PWA of the π+π− systems produced in CEP.

      Speakers: Rainer Schicker (Ruprecht Karls Universitaet Heidelberg (DE)) , Paul Alois Buhler (Stefan Meyer Institute for Subatomic Physics (SMI), Austrian Academy of Sciences (AT))
    • 3:10 PM 3:30 PM
      Diffractive cross sections 20m

      Diffractive cross sections are evaluated at 13 TeV based on the V0/AD/T0/SPD/(FMD)/(ZDC) detector combinations. Pythia_6,Pythia_8,Phojet,EPOS MC implemented for simulating soft processes.
      Luminosity, pile-up and background studies being carried out.

      Speaker: Ernesto Calvo Villar (Pontificia Universidad Catolica del Peru (PE))
    • 3:30 PM 3:50 PM
      CEP resonances 20m

      New resonance states produced in Central Exclusive Process are studied in 7 and 13 TeV data. The event sample selection criteria and sample purities are studied, PID information is optimised for the process, lego train event selection and QA discussed.

    • 3:50 PM 4:10 PM
      Analysis transverse momentum spectra in double gap events 20m

      The transverse momentum spectra of pions, kaons and protons in double gap events are analyzed, and compared to the corresponding spectra of min. bas events of the same multiplicity. Levy-Tsallis fits are applied to these transverse momentum spectra.

      Speaker: Beomkyu Kim (Inha University (KR))
    • 4:10 PM 4:40 PM
      PWA analysis note 30m

      Critical discussion of the PWA analysis note

      Speakers: Sergey Evdokimov (Institute for High Energy Physics of NRC Kurchatov Institute (R) , Serguei Sadovskyi
