Description
Understanding the behavior of cosmic ray electrons is crucial for unraveling fundamental physics questions regarding the origin, acceleration, and propagation of cosmic rays. The theoretical hypothesis of nearby sources naturally explains the bumps observed in the cosmic ray energy spectrum around the hundred TeV range, as well as the reduction in amplitude and phase reversal of anisotropy. Due to processes like inverse compton scattering, high-energy cosmic ray electrons tend to rapidly lose energy during their journey, making them superior messengers compared to other cosmic ray components when it comes to reflecting the characteristics of nearby sources. In recent years, several experiments have detected a distinctive bump structure in the electron energy spectrum at TeV energies. Theoretical calculations also indicate that, assuming the existence of nearby sources, this bump corresponds to an electron anisotropy amplitude of approximately 0.01 at TeV energies, offering a promising opportunity for observation by LHAASO WCDA. This poster provides a concise overview of our progress in analyzing the anisotropy data of cosmic ray electrons. Additionally, preliminary results of analyzing cosmic ray electrons anisotropy using LHAASO-WCDA data are shown.
