RECAST framework reinterpretation of an ATLAS Dark Matter Search constraining a model of a dark Higgs boson decaying to two $b$-quarks
The reinterpretation of a search for dark matter produced in association with a Higgs boson decaying to $b$-quarks performed with RECAST, a software framework designed to facilitate the reinterpretation of existing searches for new physics, is presented. [...]
