pi+ + p --> Sigma+ + pi+ + K0 Dear forum readers; I have a simple question. Could someone tell me the isospin is conserved in the above reaction? This is the way i understood this. LHS possible Isospin values are 1/2, 3/2 RHS possible Isospin value is 5/2 5/2 is not in LHS. so, isospin is not conserved. Is this right. I am little confused here. thanks in advanced.
