Description
Evidence for the onset of deconfinement in central Pb+Pb collisions
was reported by NA49 in fixed target measurements at beam momentum
30A GeV/c. This observation motivated the NA61/SHINE program started
in 2009 at CERN SPS, which, in particular, aims to study properties
of the onset of deconfinement by measurements of hadron production
in proton-proton, proton-nucleus and nucleus-nucleus collisions.
This contribution presents spectra of charged pions produced in p+p
interactions and ⁷Be+⁹Be collisions at 20A–158A GeV/c beam momentum.
The NA61/SHINE results will be compared with the corresponding NA49
data from central Pb+Pb collisions at the same beam momenta per
nucleon.
