摘要：
The high-energy electrons suffer severe energy loss during their propagation, owing to the Synchrotron and Inverse-Compton processes. Thus, the electrons exceeding TeV are most likely originating from few local sources, such as dark matter particle and astrophysical sources. The dipole anisotropy of the electrons is also regard as an unique signature about the nearby sources. With the merit of large detecting area and strong background suppression, the LHAASO experiment provides an opportunity on extending the detection of high-energy cosmic-ray electrons from 500 GeV to 100 TeV. In this paper, We explore the efficient rejection of hadronic background of LHAASO, in combination with KM2A and WCDA and make the expectation on the spectrum of cosmic-ray electrons and the sensitivity of dipole anisotropy with LHAASO. The influence on the research of electronic origin is also discussed.
