... SU(3)-vector bosons, the gluons, the classical theory is invariant under scaling transformations. Namely, if Aμ represents the gluon fields, and Aμ is a classical solution to the equations of motion, then so is the scaled configuration: λA(λx), for any real parameter λ. Again, the quantum structure ...

... f) Find φ(x, t). Write your answer in terms of c1 (t) and c2 (t). What does this tell you (physically) about (x, t)? What does the relative contribution of each ”basis” state look like over time? Does φ(x, t) ever equal φ(x, 0) for t 6= 0? Compute |φ(t = 0)|2 then |φ(t)|2 . Take n1 = 1, n2 = 2 and ...

In ’typical’ QFTs these can be analytically rotated back to Minkowski time. The Osterwald-Schrader theorem gives precise condition for when this is possible. Conclusion 2 wa ...
