Why there is a field algebra with a compact gauge group describing the superselection structure in particle physics
S Doplicher, JE Roberts - Communications in Mathematical Physics, 1990 - Springer
Given the local observables in the vacuum sector fulfilling a few basic principles of local
quantum theory, we show that the superselection structure, intrinsically determined a priori …
