Abstract: (Springer)
In a local relativistic quantum field theory a conserved covariant tensor current may lead to a spontaneously broken symmetry if it generates zero mass states from the vacuum (Goldstone theorem). Here it is shown that in addition it is necessary that these massless states have helicity zero if the underlaying state space has a positive metric.- field theory: goldstone theorem
- axiomatic field theory
- current: conservation law
- symmetry: broken
