在sqrt[s_{NN}]=5.02 TeV的p-Pb碰撞中，测量了重味衰变电子与带电粒子在中速（|η|<0.8）下的角相关性。对0%-20%（高）和60%-100%（低）多重度范围进行了分析。通过减去低复数事件的相关分布，可以去除高复数事件相关分布中的射流贡献。在去除喷流贡献后，方位角调制仍然存在，类似于先前对轻味强子的两粒子角相关测量的观察结果。调制的傅里叶分解结果表明，在高多重度事件中，重味衰变电子在横向动量区间1.5<p_{T}<4 GeV/c内具有正的二阶系数v_{2}，显著性大于5σ。结果与带电粒子在中速下的结果和包涵介子在正速下的结果进行了比较。在小型碰撞系统中速下测量开放重味粒子的v_{2}可以提供重要的信息，帮助解释在这些系统中观察到的各向异性。
Angular correlations between heavy-flavor decay electrons and charged particles at midrapidity (|η|<0.8) are measured in p-Pb collisions at sqrt[s_{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-flavor hadrons. A Fourier decomposition of the modulation results in a positive second-order coefficient (v_{2}) for heavy-flavor decay electrons in the transverse momentum interval 1.5<p_{T}<4 GeV/c in high-multiplicity events, with a significance larger than 5σ. The results are compared with those of charged particles at midrapidity and those of inclusive muons at forward rapidity. The v_{2} measurement of open heavy-flavor particles at midrapidity in small collision systems could provide crucial information to help interpret the anisotropies observed in such systems.
