Abstract: According to decays and structure,mesons and leptons should be unified.A new composite quantum number F′=|B+I-S| was introduced,and the basic mesons and baryons are equal-spacing and unified.The lifetime formulas and equal radio relations of heavy flavor hadrons are proposed.The triangle and tetrahedroid of quantum numbers are discussed.For quark model,some movements of micro-particles produce possibly the symmetrical magic quarks.The two-body model and subquarks are researched.Finally,some new ...
