The rapidity asymmetry is defined as the ratio of particle yields at backward rapidity ($Au$ beam direction) to those at forward rapidity ($d$ beam direction). The identified hadrons are measured in the rapidity regions $|y| < 0.5$ and $0.5 < |y| < 1.0$ for the $p_{T}$ range $2.5 < p_{T} < 10$ GeV/c. We observe significant rapidity asymmetry for charged pion and proton + antiproton production in both the rapidity regions. The asymmetry is larger for $0.5 < |y| < 1.0$ than for $|y| < 0.5$ and is almost independent of particle type. The measurements are compared to various model predictions employing multiple scattering, energy loss, nuclear shadowing, saturation effects, and recombination and also to a phenomenological parton model. We find that asymmetries are sensitive to model parameters and show model preference. The rapidity dependence of $\\pi^{-} / \\pi^{+}$ and $\\bar{p} / p$ ratios in peripheral $d+Au$ and forward neutron-tagged events are used to study the contributions of valence quarks and gluons to particle production at high $p_{T}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t1","@type":"Dataset","description":"High transverse-momentum spectra ($p_{T} > 2.5$ GeV/c) of charged pions, protons, and antiprotons for the rapidity regions $|y| < 0.5$...","name":"Table 1a"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t2","@type":"Dataset","description":"High transverse-momentum spectra ($p_{T} > 2.5$ GeV/c) of charged pions, protons, and antiprotons for the rapidity regions $|y| < 0.5$...","name":"Table 1b"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t3","@type":"Dataset","description":"High transverse-momentum spectra ($p_{T} > 2.5$ GeV/c) of charged pions, protons, and antiprotons for the rapidity regions $|y| < 0.5$...","name":"Table 1c"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t4","@type":"Dataset","description":"High transverse-momentum spectra ($p_{T} > 2.5$ GeV/c) of charged pions, protons, and antiprotons for the rapidity regions $|y| < 0.5$...","name":"Table 1d"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t5","@type":"Dataset","description":"High transverse-momentum spectra ($p_{T} > 2.5$ GeV/c) of charged pions, protons, and antiprotons for the rapidity regions $|y| < 0.5$...","name":"Table 1e"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t6","@type":"Dataset","description":"High transverse-momentum spectra ($p_{T} > 2.5$ GeV/c) of charged pions, protons, and antiprotons for the rapidity regions $|y| < 0.5$...","name":"Table 1f"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t7","@type":"Dataset","description":"High transverse-momentum spectra ($p_{T} > 2.5$ GeV/c) of charged pions, protons, and antiprotons for the rapidity regions $|y| < 0.5$...","name":"Table 1g"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t8","@type":"Dataset","description":"High transverse-momentum spectra ($p_{T} > 2.5$ GeV/c) of charged pions, protons, and antiprotons for the rapidity regions $|y| < 0.5$...","name":"Table 1h"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t9","@type":"Dataset","description":"High transverse-momentum rapidity asymmetry factor ($Y_{\\scriptsize{\\mbox{Asym}}}$) for $\\pi^{+}+\\pi^{-}$ and $p+\\bar{p}$ for $|y| < 0.5$ and $0.5 < |y| < 1.0$...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t10","@type":"Dataset","description":"Centrality dependence of high transverse-momentum rapidity asymmetry factor ($Y_{\\scriptsize{\\mbox{Asym}}}$) for $\\pi^{+}+\\pi^{-}$ and $p+\\bar{p}$ for $|y| < 0.5$ (left panels) and...","name":"Table 3a"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t11","@type":"Dataset","description":"Centrality dependence of high transverse-momentum rapidity asymmetry factor ($Y_{\\scriptsize{\\mbox{Asym}}}$) for $\\pi^{+}+\\pi^{-}$ and $p+\\bar{p}$ for $|y| < 0.5$ (left panels) and...","name":"Table 3b"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t12","@type":"Dataset","description":"Variation of nuclear modification factor ($R_{CP}$) for $\\pi^{+}+\\pi^{-}$ and $p+\\bar{p}$ with rapidity for $p_{T} > 2.5$ GeV/c for $d+Au$ collisions...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t13","@type":"Dataset","description":"Variation of $\\pi^{-} / \\pi^{+}$ and $\\bar{p} / p$ with rapidity for $2.5 < p_{T} < 10$ GeV/c for peripheral...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t14","@type":"Dataset","description":"Variation of $\\pi^{-} / \\pi^{+}$ and $\\bar{p} / p$ with rapidity for $2.5 < p_{T} < 10$ GeV/c for peripheral...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.101349.v1/t15","@type":"Dataset","description":"Variation of double ratio $(\\pi^{-} / \\pi^{+})_{\\scriptsize{\\mbox{n-tag}}}/(\\pi^{-} / \\pi^{+})_{40-100\\%}$ and $(\\bar{p} / p)_{\\scriptsize{\\mbox{n-tag}}}/(\\bar{p} / p)_{40-100\\%}$ with rapidity for $2.5 <...","name":"Table 7"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins726101?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/101349"}],"inLanguage":"en","name":"Rapidity and species dependence of particle production at large transverse momentum for d + Au collisions at s(NN)**(1/2) = 200-GeV.","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins726101?version=1","version":1}
