Production of {\pi}+ and K+ mesons in argon-nucleus interactions at 3.2 AGeV
First physics results of the BM@N experiment at the Nuclotron/NICA complex
are presented on {\pi}+ and K+ meson production in interactions of an argon
beam with fixed targets of C, Al, Cu, Sn and Pb at 3.2 AGeV. Transverse
momentum distributions, rapidity spectra and multiplicities of {\pi}+ and K+
mesons are measured. The results are compared with predictions of theoretical
models and with other measurements at lower energies.Comment: 29 pages, 20 figure
The BM@N spectrometer at the NICA accelerator complex
BM@N (Baryonic Matter at Nuclotron) is the first experiment operating and
taking data at the Nuclotron/NICA ion-accelerating complex.The aim of the BM@N
experiment is to study interactions of relativistic heavy-ion beams with fixed
targets. We present a technical description of the BM@N spectrometer including
all its subsystems.Comment: 34 pages, 47 figures, 6 table
