Energy and centrality dependence of $\overline{p}$ and $p$ production and the $\overline{\lambda}/\overline{p}$ ratio in Pb+Pb collisions between 20A GeV and 158A GeV

The transverse mass $m_{t}$ distributions for antiprotons are measured at midrapidity for minimum bias Pb+Pb collisions at 158A GeV and for central Pb+Pb collisions at 20A, 30A, 40A, and 80A GeV beam energies in the fixed target experiment NA49 at the CERN SPS. The rapidity density $dn/dy$, inverse...
