In this seminar, I will discuss the main signatures of dark matter candidates which are described by effective quantum field theories. In this kind of models, the interaction of the dark matter particle is characterized by a dimension-full parameter, that offers different possibilities than the dimensionless coupling, typical of renormalizable quantum field theories. I will analyze the abundance and the main phenomenological signatures of these candidates from astrophysical observations and their interplay with high energy or precision experiments. I will illustrate all these ideas with a particular candidate motivated from brane-world scenarios: the branon.
