15:00 - 15:10
Room: 4/3-006 - TH Conference Room
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.

Room: 4/3-006 - TH Conference Room
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.

15:30 - 15:50
Room: 4/3-006 - TH Conference Room
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.

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.
