Do not use MKS Units, 1 a.m.u = 931.5 MeV mp c²=938.272 MeV and mn c² = 939.565 MeV, me c²=0.511 MeV, mr c² = 139.567 MeV Answer question I and choose two questions from questions II, III and IV. Question I: Hadrons - Fundamental Interactions (9) Consider 1) the strong decay of a particle X into a proton and a positive pion. 2) that the relative orbital angular momentum of the system (p+) is L = 1. Calculations are made in a reference frame where X is at rest. a) Write down the equation for this decay. b) Determine the mass of particle X. c) What is its total angular momentum (I). Show your calculations. d) What is its parity? e) What is its composition in quarks. Explain your answer. f) What is its stangeness? Explain your answer Composition in quarks: p= uud, nt=ud. Hints: Positive intrinsic parity (+) is assigned to spin 1/2 fermions. Parity is conserved in strong and electromagnetic interactions.
