Localizability and the occurrence of events in dissipative quantum field theory

Localizability has been a concept of debate in the context of relativistic quantum theory. Many no-go theorems against localized particles have been developed. Some no-go theorems claimed that their result should rule out a particle ontology, some even claimed that the only possible ontology for a relativistic quantum theory is a field ontology. In this work, I will show how does dissipative quantum field theory (DQFT) escapes the assumptions of Malament's theorem by switching the ontological status of localizability from a particle's property to an event's property, while keeping a particle ontology. I will then study the occurrence of events in DQFT and discuss the ontological status of both particles and events in the theory.
