- Abstract
Assume that hadrons are formed from the emergence string. Usual string should possess two moving states: oscillation and rotation, so we propose corresponding potential and the equation of the emergence string, whose energy spectrum is namely the GMO mass formula and its modified accurate mass formula M = M0 + AS + B [I(I+1)-S²/2] These are some relations between the string and observable experimental data. Based on the Y-Q and I-U symmetries between mass and lifetime on the general SU(3) theory, we can derive the lifetime formulas: τ = A[2U(u=1)-Q/2] and τ = A'[(1/2) + 2U (2\U+1) - Q/2-Q²/3] of hyperons and mesons, which agree better with experiments. It is a new method on lifetime of hadrons described by quantum numbers. They are symmetrical with the corresponding mass formulas, and can be unified for mass and lifetime. Further, these formulas may extend to describe masses and lifetime of heavy flavor hadrons.
