Identification of deuterons in pd → dX reactions at ANKE

The collisions of protons and deuterons open up many interesting hadron physics topics, e.g., the interaction between pseudoscalar mesons and hadrons. In this regard a measurement of pd → dη p_sp has been realized at the ANKE spectrometer at the COSY accelerator of the Forschungszentrum Juelich to investigate the production mechanism of η mesons as well as their interaction with nuclear matter. Another reaction that can be studied with the same dataset is the two-pion production pd → dπ⁺π^- p_sp. In both cases the deuteron acts as an effective neutron target while the proton is handled as a spectator particle. The Fermi motion of these particles combined with the two different beam momenta (p₁ = 2.09 GeV/c and p₂ = 2.25 GeV/c) allow to study the low and high-mass enhancement in isoscalar M_ππ spectra corresponding to the ABC effect as well as total and differential cross sections. To analyze these reactions an identification of the final deuteron is of high relevance. Recent results of the identification and detector calibration procedure are presented and discussed.
