Q3) The Delta particle At+(uuu) decays to proton p(uud) and pion it* (ud) as shown att - p+ + a. Calculate the energy and momentum of the pions in the A centre-of- mass frame. m.+ = 139.6 MeV, mp = 938.3 MeV and my++ = 1232MeV. b. If the total width F(A) -120 MeV. using # =6.58x10 22 MeV s. What is the lifetime of the ? Is this interaction (strong, weak, or Electromagnetic), explain
