Partons traversing the strongly interacting medium produced in heavy-ion collisions are expected to lose energy depending on their color charge and mass. We measure the nuclear modification factors for charm- and bottom-decay electrons, defined as the ratio of yields, scaled by the number of binary nucleon-nucleon collisions, in $\\sqrt{s_{\\rm NN}}$ = 200 GeV Au+Au collisions to $p$+$p$ collisions ($R_{\\rm AA}$), or in central to peripheral Au+Au collisions ($R_{\\rm CP}$). We find the bottom-decay electron $R_{\\rm AA}$ and $R_{\\rm CP}$ to be significantly higher than that of charm-decay electrons. Model calculations including mass-dependent parton energy loss in a strongly coupled medium are consistent with the measured data. These observations provide clear evidence of mass ordering of charm and bottom quark energy loss when traversing through the strongly coupled medium created in heavy-ion collisions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t1","@type":"Dataset","description":"Fit to the $\\rm log_{10}(DCA/cm)$ of candidate electrons with $p_{\\rm T}$ $\\in$ [3.5,4.5] GeV/$c$ in 0-80% Au+Au collisions at $\\sqrt{s_{\\rm...","name":"Figure 5"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t2","@type":"Dataset","description":"Invariant yield of the electrons from decays of prompt $J/\\psi$, $\\Upsilon$, Drell-Yan and light vector mesons in 0-80% Au+Au collisions...","name":"Figure 6"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t3","@type":"Dataset","description":"Invariant yield of heavy flavor hadron decayed electrons in 0-80% Au+Au collisions at $\\sqrt{s_{\\rm NN}}$ = 200 GeV.","name":"Figure 7"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t4","@type":"Dataset","description":"Fraction of bottom hadron decayed electrons in 0-80% Au+Au collisions at $\\sqrt{s_{\\rm NN}}$ = 200 GeV.","name":"Figure 8a"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t5","@type":"Dataset","description":"Fraction of bottom hadron decayed electrons in 0-20% and 20-40% Au+Au collisions at $\\sqrt{s_{\\rm NN}}$ = 200 GeV.","name":"Figure 8b: 0-20% and 20-40%"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t6","@type":"Dataset","description":"Fraction of bottom hadron decayed electrons in 40-80% Au+Au collisions at $\\sqrt{s_{\\rm NN}}$ = 200 GeV.","name":"Figure 8b: 40-80%"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t7","@type":"Dataset","description":"Nuclear modification factor $R_{\\rm AA}$ of inclusive heavy flavor decayed electrons in 0-80% Au+Au collisions at $\\sqrt{s_{\\rm NN}}$ = 200...","name":"Figure 9a"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t8","@type":"Dataset","description":"Nuclear modification factor $R_{\\rm AA}$ of bottom- and charm-decay electrons in 0-80% Au+Au collisions at $\\sqrt{s_{\\rm NN}}$ = 200 GeV....","name":"Figure 9b"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t9","@type":"Dataset","description":"Nuclear modification factor $R_{\\rm AA}$ ratio of bottom- to charm-decay electrons in 0-80% Au+Au collisions at $\\sqrt{s_{\\rm NN}}$ = 200...","name":"Figure 10a"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t10","@type":"Dataset","description":"Null hypothesis for the nuclear modification factor $R_{\\rm AA}$ ratio of bottom- to charm-decay electrons in 0-80% Au+Au collisions at...","name":"Figure 10a null hyp"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t11","@type":"Dataset","description":"Nuclear modification factor $R_{\\rm CP}$ ratio of bottom- and charm-decay electrons in 0-80% Au+Au collisions at $\\sqrt{s_{\\rm NN}}$ = 200...","name":"Figure 10b"},{"@id":"https://doi.org/10.17182/hepdata.115424.v1/t12","@type":"Dataset","description":"Null hypotheses for the nuclear modification factor $R_{\\rm CP}$ ratio of bottom- and charm-decay electrons in 0-80% Au+Au collisions at...","name":"Figure 10b null hyp"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1978766?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/115424"}],"inLanguage":"en","name":"Evidence of Mass Ordering of Charm and Bottom Quark Energy Loss in Au+Au Collisions at RHIC","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1978766?version=1","version":1}
