Descrição
Despite the many gravitational pieces of evidence about the existence of Dark Matter, its microscopic nature remains unknown. During the last decades, a considerable effort was deposited in this subject. Although many constraints have been made, no single Dark Matter particle event was detected in experiments across the globe. As new approaches were demanded, a well-motivated class of models was proposed in the last decade, the Boosted Dark Matter. The main feature of these models is the capacity to combine the most attractive characteristics of the WIMP models with new perspectives to particle detection.
Boosted DM models consist of postulating a multi-component Dark Sector in which a new type of DM particle is produced in later times of the Universe by annihilation or semi-annihilation of the cold and dominant dark matter component. Due to the mass hierarchy, this new particle receives a boost. In this context, the Deep Underground Neutrino Experiment (DUNE), currently under construction in the Sanford Underground Research Facility in the US, is an excellent opportunity to study these models and will be able to make a possible discovery. This work presents the DUNE’s sensitivity for Boosted DM from the Sun with a complete simulation and reconstruction of the detector capabilities.
