This propagator 50 4 Theories and Lagrangians II: Introducing Gauge Fields admits a path integral representation, where the integration has to be done taking into account that there are two classes of paths that are topologically non-equivalent: those passing through the upper and the lower slits. 11) γ where the second term in the last equation is a line integral along the particle trajectory γ . Using Stokes’ theorem and ∇ × A = 0 we find that the value of this term only depends on the topological class of γ , but not in the particular curve within each class.

28 2 From Classical to Quantum Fields out. A salient feature of path integrals to be noticed here is that they automatically implement time ordering. Path integrals are not easy to evaluate. In fact they cannot be computed exactly in most cases. This notwithstanding, path integrals provide an extremely useful tool in quantum field theory. They can be formally manipulated to obtain results whose derivation using canonical quantization methods would be much harder. The only path integrals that can be computed exactly are the so-called Gaussian integrals where the action functional of the theory is at most quadratic in the fields.

47) on the left respectively by (/k ∓ m) we find that the momentum is on the mass shell, k 2 = m 2 . Hence, the wave function for both positive- and negative-energy solutions is labelled by the three-momentum k of the particle, u(k, s), v(k, s). Before proceeding any further we consider the case of a massless Dirac fermion. 48) and similarly for v(k, s). , the projection of the spin along the direction of motion) and chirality (the eigenvalue of the γ5 matrix) are equivalent concepts. In this case the helicity of the spinor is a relativistic invariant.
