Le résumé fourni par la source
The BM@N experiment (Baryonic Matter at the Nuclotron) is the first fixed-target experiment at the JINR NICA accelerator complex. In this work, data on the interactions of a carbon-ion beam with kinetic energies of 4.0A~GeV and 4.5A~GeV with C, Al, Cu, and Pb targets are used to measure transverse momentum spectra and rapidity distributions of $Λ$ hyperon yields. The results are compared with the predictions of DCM-SMM, UrQMD, and PHSD transport models and with the $Λ$ yield measurements in other experiments at similar collision energies.
