The production of beauty hadrons was measured via semi-leptonic decays at mid-rapidity with the ALICE detector at the LHC in the transverse momentum interval $1 <p_{\\rm T}<8~\\textrm{GeV}/c$ in minimum-bias p-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$~TeV and in $1.3 <p_{\\rm T}<8~\\textrm{GeV}/c$ in the 20\\% most central Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 2.76$~TeV. The pp reference spectra at $\\sqrt{s} = 5.02$~TeV and $\\sqrt{s} = 2.76$~TeV, needed for the calculation of the nuclear modification factors $R_{\\rm pPb}$ and $R_{\\rm PbPb}$, were obtained by a pQCD-driven scaling of the cross section of electrons from beauty-hadron decays measured at $\\sqrt{s} = 7$ TeV. In the $p_{\\rm T}$ interval $3 <p_{\\rm T}<8~\\textrm{GeV}/c$ a suppression of the yield of electrons from beauty-hadron decays is observed in Pb-Pb compared to pp collisions. Towards lower $p_{\\rm T}$, the $R_{\\rm PbPb}$ values increase with large systematic uncertainties. The $R_{\\rm pPb}$ is consistent with unity within systematic uncertainties and is well described by theoretical calculations that include cold nuclear matter effects in p-Pb collisions. The measured $R_{\\rm pPb}$ and these calculations indicate that cold nuclear matter effects are small at high transverse momentum also in Pb-Pb collisions. Therefore, the observed reduction of $R_{\\rm PbPb}$ below unity at high $p_{\\rm T}$ may be ascribed to an effect of the hot and dense medium formed in Pb-Pb collisions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.77904.v1/t1","@type":"Dataset","description":"Invariant cross section of electrons from beauty-hadron decays as a function of transverse momentum in minimum-bias p--Pb collisions in the...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.77904.v1/t2","@type":"Dataset","description":"Invariant yield of electrons from beauty-hadron decays as a function of transverse momentum in 20% most central Pb--Pb collisions.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.77904.v1/t3","@type":"Dataset","description":"Nuclear modification factor $R_{\\text{pA}}$ of electrons from beauty-hadron decays as a function of transverse momentum for minimum-bias p--Pb collisions in...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.77904.v1/t4","@type":"Dataset","description":"Nuclear modification factor $R_{\\text{AA}}$ of electrons from beauty-hadron decays as a function of transverse momentum for 20% most central Pb--Pb...","name":"Table 4"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1486391?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/77904"}],"inLanguage":"en","name":"Measurement of electrons from beauty-hadron decays in p-Pb collisions at $\\mathbf{\\sqrt{s_{\\rm NN}}=5.02}$ TeV and Pb-Pb collisions at $\\mathbf{\\sqrt{s_{\\rm NN}}=2.76}$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1486391?version=1","version":1}
