comment Why are only derivatives to the first order relevant?
Thanks for the answer. Unfortunately the paper seems to involve involves Gauge theory, something which I'm not very familiar with. I was hoping for a simple example form classical mechanics which involves a higher order Lagrangian. Or perhaps I need to venture beyond mechanics to find a solution?

If you are right, then my answer is wrong. Could you provide an example of a Lagrangian which involves higher derivatives?
