Spacetimes of maximal proper acceleration and muon mean lifetime

In this paper, it is shown that in spacetimes of maximal proper acceleration, there is a reduction of the mean lifetime of the muon. We consider several candidates for the maximal proper acceleration. For all of them, the induced corrections are small, but for the case when the maximal proper acceleration is identified with Schwinger’s acceleration, the effect is detectable in future muon collider facilities.
