Search for Dark Matter Produced in Association with a Higgs Boson decaying to bb¯ at √s=13 TeV with the ATLAS Detector using 79.8 fb-1 of proton-proton collision data
(2018) 10th International Workshop on Boosted Object Phenomenology, Reconstruction and Searches in HEP- Abstract
- A search for dark matter produced in association with a Higgs boson decaying to b-quarks is performed using pp collisions at a centre-of-mass energy of √s=13 TeV. The dataset has an integrated luminosity of 79.8 fb−1 and was recorded with the ATLAS detector at the Large Hadron Collider. Selected collision events comprise large missing transverse momentum and either two b-tagged small radius jets or a single large radius jet containing two b-tagged subjets. The reconstruction of these subjets is based on a jet algorithm that uses inner detector tracks as inputs and a radius parameter that decreases as the subjet transverse momentum increases. The observed data are in agreement with the Standard Model predictions. The results are... (More)

The reconstruction of these subjets is based on a jet algorithm that uses inner detector tracks as inputs and a radius parameter that decreases as the subjet transverse momentum increases. The observed data are in agreement with the Standard Model predictions. The results are interpreted in the context of a simplified model (Z′-2HDM) which describes the interaction of dark matter and Standard Model particles via new heavy mediator particles. Masses of the Z′ are excluded up to 2.8 TeV depending on the choices for other model parameters. (Less)
