Abstract：
The pionic two body decay process of the proton is discussed in the SU(5) grand unification theory by using the field-current relation of the composite particle and the soft pion approximations. We connect the proton decay process with the J/ψ→pp decay amplitude and determine the wavefunction at the origin from the experimental value of the decay rate J/ψ→pp, hence we can obtain the value of the proton decay lifetime. In order to estimate the uncertainty of the proton decay lifetime due to the proton wavefunction at the origin, the lower bound of it is analysed by using an interesting model. If taking Λ_MS=200 MeV, it will be a serious test for the minimal SU(5) grand unified gauge theory. It should be noted that this method which connect the proton decay process with other relavant processes will be very useful to determine the proton decay lifetime.
