Description
The understanding of Dark Matter (DM) is now reaching to an important point. The DM direct detection experiments have not found any signal of DM yet constraining large portions of the DM mass-cross section parameter space. Furthermore, these experiments are now becoming sensitive to areas where the Standard Model (SM) neutrino background (known as neutrino floor) starts to be important. Crossing this point would make the search for DM more difficult due to the neutrino background signal in the detectors. It seems like a not-so pleasant scenario for the typical DM candidate. However, those all these bounds are being calculated assuming that DM interactions are isospin conserving. If one extends the SM to an have isospin violating (IV) connection to the dark sector the overall scene can change dramatically. In this seminar we will revisit the consequences of isospin violating DM (IVDM) mediated by a local U(1) gauge boson. We will study the phenomenology of IV interactions to both direct detection bounds and the neutrino floor and how this can change the overall scene. Furthermore, we will discuss a possible UV origin of IV models mediated by a Z' and also its phenomenology at colliders.
