Pion induced reactions

Pion-proton elastic scattering and normalization (Izabella Ciepal, Witek Przygoda)

Two pion exclusive channels (Witek Przygoda, Izabella Ciepal, Andrey Sarantsev)

Dielectron exclusive channel (Pablo Rodrigez, Federicco Scozzi)

Dilepton analysis (July 2018)

  • 3-dim acceptance and efficiency matrices calculated from GEANT4 simulations of electrons/positrons with flat momentum distributions (p<700 MeV /c).X=theta (deg) 45 bins (0.,90.) ;Y=phi (deg) 90 bins (0.,360.); Z=p (MeV /c) 40 bins (0.,800.);
  • accep_matrix_ele.root: electron acceptance
  • accep_matrix_pos.root: positron acceptance : geometrical acceptance matrices for electrons and positrons for true values of theta,phi,p .
  • matrix_reco_ele_smearing_white.root: electron efficiency
  • matrix_reco_pos_smearing_white.root: positron efficiency : contains efficiency matrices for electrons and positrons for the old RICH digitizer defined as N(p_rec,theta_rec,phi_rec)/ N(p_true, theta_true, phi_true)
  • data and simulation (using PLUTO ρ and old RICH digitizer) events for extraction of Spin Density Matrix coefficients (Andrey's procedure)
  • tar file with Andrey's code. Instructions can be found in the README.
  • files with events generated with the GSI model (old version) in 4π N1440,N1520,N1520+N1440,N1520-N1440: original files and files with appropriate format to be used by the fitting code.

General infromation on experiment can be found on Pion Beam page
