Figure 4

Distance of closest approach in the transverseplane to the primary vertex (DCA$_{xy}$) of deuterons(solid circles) and anti-deuterons (hollow circles) for the $p_{\text{T}}$ bins$0.8< p_{\text{T}}< 0.9$~GeV/$c$ (left) and $1.9< p_{\text{T}}< 2.0$~GeV/$c$(right). A large background distribution of secondary deuterons isclearly visible in the left panel.
