LHAASO directly observes the <math><mn>1.42</mn><mspace width=\"0.25em\"></mspace><mtext>PeV</mtext></math> highest-energy photon. By adopting the synchrotion self-Compton model, LHAASO also suggests that the <math><mn>1.12</mn><mspace width=\"0.25em\"></mspace><mtext>PeV</mtext></math> high-energy photon from Crab Nebula corresponds to a <math><mn>2.3</mn><mspace width=\"0.25em\"></mspace><mtext>PeV</mtext></math> high-energy electron. We study the <math><mn>1.42</mn><mspace width=\"0.25em\"></mspace><mtext>PeV</mtext></math> photon decay and the <math><mn>2.3</mn><mspace width=\"0.25em\"></mspace><mtext>PeV</mtext></math> electron decay to perform a joint analysis on photon and electron two-dimensional Lorentz violation (LV) parameter plane. Our analysis is systematic and comprehensive, and we naturally get the strictest constraints from merely considering photon LV effect in photon decay and electron LV effect in electron decay. Our result also permits the parameter space for new physics beyond relativity."
