We upgraded Indico to version 3.0. The new search is now available as well.

Description

Assume that dark matter couples mostly to the top-quark. This hypothesis is well motivated in models with scalar mediators, where flavor-hierarchical couplings to quarks prevent large flavor-changing neutral currents. In this talk, we discuss searches for dark matter produced in association with top-quarks at the LHC. We propose single-top-associated production as a new search channel for dark matter. Being complementary to exisiting searches with top pairs, the new single-top channel enhances the discovery potential for dark matter in future LHC analyses.
