Now assume that you are in the center of momentum frame for the initial state. This means that the total four-momentum is simply Q = (Ecm,0,0,0) (7) Use the total four-momentum conserving 8-function to integrate over the three-momentum of the second final state particle, đp2. It should be easy to find that dp = (8) 2E (28)8(Ecm - E - Ey) | allz - S 26,263
Pass to spherical coordinates for pi. Note that the energies are independent of the angular coordinates. They do, however, depend on the magnitude pıl = |P2) = p. Integrate over the remaining 8-function to show that d112 - IL/ 6. 1 P 16n? Есм do d cos 0
