Question

7. Δ baryons are 1- excited states of the nucleon. Consider all possible decays of the Δ baryon into a pion and a nucleon: 0 0 (a) First, do a simple check of what is in Das-Ferbel, Table 10.2. Show your work and obtain the solutions shown in the table. b) Next, use the isospin notation: 2' 2 2' 2 to represent the Δ , which we can consider as made of a neutron and π orbiting each other. Then, apply the isospin raising operator (formally identical to the spin raising operator we used in lecture 10) to get the state , ,-) operator to the left and right of Eq.2 and show you get agreement with the numbers in Table 10.2 for the predicted branches of the A) into n + π0 and ptT_. which represents the A°. Do this applying the
