Information about seminar

  1. Seminar topic: “Is there diffraction dissociation of nuclear nucleons in nucleus-nucleus interactions”

    Authors: Vladimir Uzhinsky, Aida Galoyan (VBLHEP JINR)

    Speaker: Vladimir Uzhinsky

    Abstract:

    A new algorithm of accounting of the diffraction dissociation of nucleons in nucleus-nucleus interactions is proposed. A good description of the BMN collaboration data on 𝜋+ meson production in Ar – nucleus interactions has been reached, though there are left some problems.


  2. Seminar topic: “Towards understanding of Ks0 meson production in hadronic interactions”

    Authors: Vladimir Uzhinsky, Aida Galoyan (VBLHEP JINR), Alberto Ribon (CERN)

    Speaker: Aida Galoyan

    Abstract:

    It is shown that the recent data by the NA61/SHINE collaboration on Ks0 meson production in pp interactions at Plab = 31, 40, 80 and 158 GeV/c are well described by the Geant4 FTF model without any tuning of the model parameters.


  3. Seminar topic: “Microscopic analysis of elastic scattering and transfer reaction in the collision at energy 58 MeV”

    Authors: Elena Zemlyanaya, Konstantin Lukyanov, Valery Lukyanov (BLTP JINR), Yuri Penionzhkevich (FLNR JINR), Yuri Sobolev (FLNR JINR), Sergei Stukalov (FLNR JINR)

    Speaker: Elena Zemlyanaya

    Abstract:

    Analysis of cross sections of the 7Li+10B elastic scattering and the transfer reaction 7Li+10B → 6Li+11B at the beam energy Elab = 58 MeV is carried out by using the microscopic optical potential and the DWBA approach. The results are discussed in comparison with experimental data obtained in 2023 at the U-400 cyclotron in FLNR JINR.


  4. Seminar topic: “Target dependence of the isotope distributions in heavy-ion reactions at Fermi energies”

    Authors: Tatiana Mikhaylova, Erdemchimeg Batchuluun (FLNR JINR)

    Speaker: Tatiana Mikhaylova

    Abstract:

    In this report the experimental ratio of cross-sections obtained in the reactions on heavy 181Ta and light 9Be targets in the collision with projectile 18O at 35 MeV per nucleon is compared with the predictions of transport-statistical approach BNV-SMM and several frequently used models. The difference in the model results is discussed.
