We report on the measurement of $\\rm{J}/\\psi$ production in the dielectron channel at mid-rapidity (|y|<1) in p+p and d+Au collisions at $\\sqrt{s_{NN}}$ = 200 GeV from the STAR experiment at the Relativistic Heavy Ion Collider. The transverse momentum $p_{T}$ spectra in p+p for $p_{T}$ < 4 GeV/c and d+Au collisions for $p_{T}$ < 3 GeV/c are presented. These measurements extend the STAR coverage for $\\rm{J}/\\psi$ production in p+p collisions to low $p_{T}$. The $<p_{T}^{2}>$ from the measured $\\rm{J}/\\psi$ invariant cross section in p+p and d+Au collisions are evaluated and compared to similar measurements at other collision energies. The nuclear modification factor for $\\rm{J}/\\psi$ is extracted as a function of $p_{T}$ and collision centrality in d+Au and compared to model calculations using the modified nuclear Parton Distribution Function and a final-state $\\rm{J}/\\psi$ nuclear absorption cross section.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.73526.v1/t1","@type":"Dataset","description":"The mean square of $p_T$.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.73526.v1/t2","@type":"Dataset","description":"Nuclear absorption cross section.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.73526.v1/t3","@type":"Dataset","description":"The nuclear modicifation factor vs. $p_T$ for $J\\psi$ with |y| < 1 in 0-100 percent central d+Au collisions.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.73526.v1/t4","@type":"Dataset","description":"Nuclear modicifation factor vs. N_coll $J\\psi$ with|y|<1 and pT < 3 GeV/c in d Au collisions.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.73526.v1/t5","@type":"Dataset","description":"The invariant cross section versus transverse momentum for J/$\\psi$ with $|y|\\lt 1$ in $p+p$ collisions.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.73526.v1/t6","@type":"Dataset","description":"The invariant yield versus transverse momentum for $J/\\Psi$ with |y| < 1 in 0 - 100 percent central d+Au collisions.","name":"Table 6"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1420183?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/73526"}],"inLanguage":"en","name":"$\\rm{J}/\\psi$ production at low transverse momentum in p+p and d+Au collisions at $\\sqrt{s_{NN}}$ = 200 GeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1420183?version=1","version":1}
