Abstract
In this article, we present the strategy of analysis for searching the dark matter particles produced in association with the Standard Model Higgs boson (h) predicted within the “2HDM + a” model in the CMS (LHC) experiment. The strategy is optimized for analysis using the 2018 data for pp collisions at 13 TeV corresponding to an integral luminosity of ~60 fb–1. It is shown that the maximum sensitivity to the expected signal can be achieved by introducing two categories of analysis corresponding to large and small values of the transverse momentum of the h boson.
