11. It is only the baryon flavor that changes, here labelled as the isospin . 12. Quarks also carry electric charge and weak isospin . 13. Attempts have been made to promote isospin from a global to a local symmetry. 14. Isospin and intrinsic spin are related under this SU ( 2 ) symmetry group.15. The young physicist glibly stated that certain bizarre subatomic particles had an isospin of 1. 16. According to the Noether theorem, isospin is conserved with respect to the strong interaction. 17. This unknown excitation was later dubbed " isospin " by Eugene Wigner in 1937. 18. A gauge connection would then describe how to transform isospin along a path between two points. 19. DCC's are regions where the chiral field is partially aligned in a isospin direction. 20. Under the isospin model, they were considered to be a single particle in different charged states.
