The elliptic flow of electrons from heavy-flavour hadron decays at mid-rapidity ($|y|$ $<$ 0.7) is measured in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 2.76$ TeV with ALICE at the LHC. The particle azimuthal distribution with respect to the reaction plane can be parametrized with a Fourier expansion, where the second coefficient ($v_{\\rm 2}$) represents the elliptic flow. The $v_{\\rm 2}$ coefficient of inclusive electrons is measured in three centrality classes (0-10%, 10-20% and 20-40%) with the event plane and the scalar product methods in the transverse momentum ($p_{\\rm T}$) intervals 0.5-13 GeV/$c$ and 0.5-8 GeV/$c$, respectively. After subtracting the background, mainly from photon conversions and Dalitz decays of neutral mesons, a positive $v_{\\rm 2}$ of electrons from heavy-flavour hadron decays is observed in all centrality classes, with a maximum significance of $5.9\\sigma$ in the interval $2 <$ $p_{\\rm T}$ $<$ 2.5 GeV/$c$ in semi-central collisions (20-40%). The value of $v_{\\rm 2}$ decreases towards more central collisions at low and intermediate $p_{\\rm T}$ (0.5 $<$ $p_{\\rm T}$ $<$ 3 GeV/$c$). The $v_{\\rm 2}$ of electrons from heavy-flavour hadron decays at mid-rapidity is found to be similar to the one of muons from heavy-flavour hadron decays at forward rapidity (2.5 $<$ $y$ $<$ 4). The results are described within uncertainties by model calculations including substantial elastic interactions of heavy quarks with an expanding strongly-interacting medium.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.73972.v1/t1","@type":"Dataset","description":"Elliptic flow of electrons from heavy flavour hadron decays as a function of transverse momentum at midrapidity in the 0--10%...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.73972.v1/t2","@type":"Dataset","description":"Elliptic flow of electrons from heavy flavour hadron decays as a function of transverse momentum at midrapidity in the 10--20%...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.73972.v1/t3","@type":"Dataset","description":"Elliptic flow of electrons from heavy flavour hadron decays as a function of transverse momentum at midrapidity in the 20--40%...","name":"Table 3"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1466626?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/73972"}],"inLanguage":"en","name":"Elliptic flow of electrons from heavy-flavour hadron decays at mid-rapidity in Pb-Pb collisions at $\\mathbf{\\sqrt{s_\\mathrm{NN}}}$ = 2.76 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1466626?version=1","version":1}
