    "abstract": "Despite the fact that the fundamental physical laws are symmetric in time,\nmost observed processes do not show this symmetry. Especially the phenomenon of\ndecay seems to involve a kind of irreversibility that makes the definition of a\nmicroscopic arrow of time possible. Such an intrinsic irreversibility is\nincorporated within the Rigged Hilbert Space quantum mechanics of the Brussels\nSchool, contrasting to the statements of standard quantum mechanics. As shown\nin this paper, the formalism bears significant advantages in the description of\ndecaying systems, however the breaking of time symmetry can be avoided.",
