AbstractAbstract
[en] Direct production of charmed baryons Λc+ on carbon, aluminium and copper targets has been observed in neutron-nucleus interactions at ∼ 58 GeV. It has been found that an A-dependence of Λc+-baryon inclusive production cross section in a kinematical region of 0.5 ≤ x ≤ 1 and Ptr ≤ 1 GeV/c, fitted as σ(A) ∼ Aα gives α=0.73±0.20. This is the first experimental results on the A-dependence of the charmed baryon production cross section. The experiment has been performed at the 70 GeV Serpukhov accelerator by means of the BIS-2 spectrometer of JINR
