Figure 3

In the upper panel the deuteron \pt\ spectra are shown for the three centrality intervals extended to high \pt\ with the TOF and HMPID analyses In the lower panels the ratios of anti-deuterons and deuterons are shown for the 0--10\%, 10--20\% and 20--40\% centrality intervals, from top to bottom The ratios are consistent with unity over the whole \pt\ range covered by the presented analyses.
