K_e3 semileptonic decay

    1. The problem statement, all variables and given/known data

    I have to calculate the decay rate of the following process:

    K^{+} ---> pion^{0}+e^{+}+neutrino

    2. Relevant equations

    the differential decay rate for this process is

    2(p*p_neutrino)(p*p_electron)-(p_neutrino*p_electron)(p^2) * diracdelta(p_kaon - p_pion - p_electron - p_neutrino) * [d^3p_pion/E_pion]*[d^3p_electron/E_electron]*[d^3p_neutrino/E_neutrino] ,

    where p=p_kaon+p_pion

    3. The attempt at a solution

    I think it would be better calculate in the rest frame of kaon....or not?

    So, the exercise is: I have to integrate this rate for the final state of the particles, but how it goes?

    thanks
