This is a proceedings for PPAP 2019. Thanks to speakers and participants, the workshop was timely and lively. The topics cover the uniqueness of the standard model and beyond, flavor and modular symmetries from string compactification, D meson mixing, Dark matter and Dark energy, Lorentz invariant and CPT breaking effect, modular symmetry and flavor mixing and masses, relation between CP violation of quark and lepton, and Higgs mass formulas in the left-right model.
