Abstract
The NA61/SHINE programme on strong interactions covers the study of the onset of deconfinement and aims to discover the critical point of strongly interacting matter by performing an energy and system-size scan over the full CERN SPS momentum range. So far the scans of p+p, 7Be+9Be, as well as Ar+Sc have been completed. Results from p+p and Be+Be collisions are now emerging, in particular the energy dependence of hadron spectra and yields. Status and preliminary results from this effort will be presented.
Highlights
The n- spectra may be obtained by subtracting the small non-pion contribution from the overall spectra for negatively charged hadrons
3. p + p results The results presented below were obtained for identified hadrons produced in inelastic p+ p interactions at 20, 31, 40, 80 and 158 G eV /c [4]
While a / a LS and a / y beam are smaller in p + p than P b + P b collisions, no qualitative difference is observed for their energy dependence
Summary
