DESCRIPTION:Speakers: Nadezhda Ladygina (JINR)\nThe reaction of $\\pi$ -me
 son production in proton-proton collision is considered at an energy of 80
 0 MeV. Two reaction mechanisms are taken into account to describe the proc
 ess. One of them is the one-pion exchange mechanism. \nThe pion-nucleon in
 teraction is described by an energy-dependent parameterization.\n\nAlso\, 
 the final state interaction between the two nucleons is included in the co
 nsideration. This mechanism is described by the NN wave function\, which i
 s obtained by the matrix inversion method. As a result\, the reaction ampl
 itude is determined\, which allows calculating both the differential cross
  section and any polarization observables.\n\nhttps://indico.particle.meph
