Search for inelastic Dark Matter with a Dark Higgs at Belle II — •Patrick Ecker, Torben Ferber, Pablo Goldenzweig, and Jonas Eppelt for the Belle II collaboration — Karlsruhe Institute of Technology, Karlsruhe, Germany

Although the Standard Model (SM) of particle physics describes most of the phenomena observed in our universe very well, there are still some observations where the SM lacks to provide an explanation. One of these observations is the presence of Dark Matter which is very well motivated. Nevertheless, it is still not clear which particles make up this Dark Matter.

This talk will present a sensitivity study based on Monte Carlo simulations for a search for an inelastic Dark Matter model which involves the presence of a Dark Higgs boson. This model has a signature of up to two displaced vertices, one from the resonant decay of the Dark Higgs and another non-resonant one emerging from the decay of the involved Dark Matter particles.
