DESCRIPTION:Speakers: Aida Galoyan (Joint Institute for Nuclear Research)\
 nAt future NICA/SPD experiment\,  polarized and un-polarized proton-proton
   (pp)\, deuteron-deuteron (dd)\, and\, possible\, helium-helium (HeHe) in
 teractions will be investigated. Therefore\, Monte Carlo simulations of li
 ght nucleus-nucleus inelastic and elastic collisions are needed for design
 ing and physical program development of the SPD experiment.\nOur work is a
 imed to create a code for simulations of elastic interactions of light nuc
 lei\, especially of dd-scatterings.  At the beginning\, we used Geant4 mod
 els for elastic scattering’s modeling  – ElasticDIFF and ElasticCHIPS.
   It was observed that Geant4 elastic models can describe the elastic inte
 ractions at low four-momentum transfer (t) and low energies. However\, the
 y are not applicable to the elastic dd interactions at higher energies. \n
 Then\, we have applied codes based on the Glauber theoretical model to ela
 stic dd interactions.  Quite good results have been obtained when comparin
 g experimental data on dd elastic interactions at high energies and our ca
 lculations based on these codes. Earlier\, codes based on Glauber approach
  were written in FORTRAN. Using these in frameworks  of NICA experiments i
 s cumbersome. Thus\, we have created a new C++ code based on Glauber model
 \, starting from the old FORTRAN codes. Some results obtained with the new
  C++ code will be presented in our report. The new code allows also to cal
 culate elastic interactions of light nuclei like pp\, dd\, HeHe\, and pHe.
