The asymmetries are consistent with zero, similar to those for midrapidity neutral pions and eta mesons produced in $p+p$ collisions. These measurements show no evidence of additional effects that could potentially arise from the more complex partonic environment present in proton-nucleus collisions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.139098.v1/t1","@type":"Dataset","description":"Data from Figure 2 (a) of the $\\pi^{0}$ transverse single-spin asymmetry in $\\sqrt{s_{NN}}=200$ GeV $p^{\\uparrow}+$Au and $p^{\\uparrow}+$Al collisions as a...","name":"Figure 2 (a)"},{"@id":"https://doi.org/10.17182/hepdata.139098.v1/t2","@type":"Dataset","description":"Data from Figure 2 (b) of the $\\eta$ transverse single-spin asymmetry in $\\sqrt{s_{NN}}=200$ GeV $p^{\\uparrow}+$Au and $p^{\\uparrow}+$Al collisions as a...","name":"Figure 2 (b)"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2641468?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/139098"}],"inLanguage":"en","name":"Transverse single-spin asymmetry of midrapidity $\\pi^{0}$ and $\\eta$ mesons in $p$+Au and $p$+Al collisions at $\\sqrt{s_{_{NN}}}=$ 200 GeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2641468?version=1","version":1}
