Angular correlations between heavy-flavour decay electrons and charged particles at mid-rapidity ($|\\eta| < 0.8$) are measured in p--Pb collisions at $\\sqrt{s_{\\rm{NN}}} = 5.02$ TeV. The analysis is carried out for the 0--20\\% (high) and 60--100\\% (low) multiplicity ranges. The jet contribution in the correlation distribution from high-multiplicity events is removed by subtracting the distribution from low-multiplicity events. An azimuthal  modulation remains after removing the jet contribution, similar to previous observations in two-particle angular correlation measurements for light-flavour hadrons. A Fourier decomposition of the modulation results in a positive second-order coefficient ($v_{2}$) for heavy-flavour decay electrons in the transverse momentum interval $1.5 < p_{\\rm{T}} < 4$~GeV/$c$ in high-multiplicity events, with a significance larger than $5\\sigma$.  The results are compared with those of charged particles at mid-rapidity and of inclusive muons at forward rapidity. This is the first $v_2$ measurement of open heavy-flavour particles at mid-rapidity in small collision systems, which could provide crucial information to help interpret the anisotropies observed in such systems.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.87259.v1/t1","@type":"Dataset","description":"$V_{2\\Delta}^{HFe-ch}$ in bins of $p_T$ for p-Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV.
