added a little more to worldline formalism.

In particular I added mentioning of this old but curious fact, which I only just learned of from looking again at the review Schubert 96:

In (Metsaev-Tseytlin 88) the 1-loop beta function for pure Yang-Mills theory was obtained as the point-particle limit of the partition function of a bosonic open string in a Yang-Mills background field. This provided a theoretical explanation for the observation, made earlier in (Nepomechie 83) that when computed via dimensional regularization then this beta function coefficient of Yang-Mills theory vanishes in spacetime dimension 26. This of course is the critical dimension of the bosonic string.

1. Added some more recent references to relevant papers

WorldlineWalker

2. Added reference to Feynman’s observation regarding a particle path integral representation of the propagator in scalar QED as far back as 1950.

Added reference to the famous “AAM” paper on worldline instantons and pair creation
