Abstract：
The proton and meson are regarded as bound state which are composed of quarks. The pionic two-body decay amplitude of the proton in the SU(5) grand unification gauge theory is computed by using field theory method[1]. This amplitude is contained an overlap integral of the space wave functions between the proton and pion, with the naive quark-parton idea, to the lowest approximation, this overlap integral is ∫d⁴u₁ψ^π*(0, u₁)ψ^P(u₁, 0, 0). By using the wavefunction of ground state for the relativistic harmonicoscillator potential, we have computed the partial decay rate of the process p→π⁰e⁺. The result is (2.1×10²⁹ years) and (4.4×10³¹ years) for m_x=10¹⁴GeV and m_x=10¹⁴GeV, respectively.
