Some Physical Aspects of Liouville String Dynamics

We discuss some physical aspects of our Liouville approach to non-critical strings, including the emergence of a microscopic arrow of time, effective field theories as classical “pointer” states in theory space, CPT violation and the possible apparent non-conservation of angular momentum. We also review the application of a phenomenological parametrization of this formalism to the neutral kaon system. a Theory Division, CERN, CH-1211, Geneva, Switzerland, b Theoretical Physics Laboratory, ENSLAPP, Chemin de Bellevue, Annecy-le-Vieux, France, and On leave from S.E.R.C.
