Abstract

In the coming decades, within the framework of current research programs, searches and detailed studies of new light mediator particles that mediate interactions between the dark sector and Standard Model particles will be conducted. In this work, we present a theoretical study of the search for associative light dark matter production with tau leptons in the final state, mediated by massive scalar and vector mediator particles, in electron–positron collisions in a model with an additional \(U(1)\) gauge symmetry and an extra scalar field.
