An exploration of such scenarios is presented, considering final states with missing transverse momentum and b-tagged jets consistent with a Higgs boson. The analysis uses proton-proton collision data at a centre-of-mass energy of 13 TeV recorded by the ATLAS experiment at the LHC during Run 2, amounting to an integrated luminosity of 139 fb−1. The analysis, when compared with previous searches, benefits from a larger dataset, but also has further improvements providing sensitivity to a wider spectrum of signal scenarios. These improvements include both an optimised event selection and advances in the object identification, such as the use of the likelihood-based significance of the missing transverse momentum and variable-radius track-jets. No significant deviation from Standard Model expectations is observed. Limits are set, at 95% confidence level, in two benchmark models with two Higgs doublets extended by either a heavy vector boson Z′ or a pseudoscalar singlet a and which both provide a dark matter candidate χ. In the case of the two-Higgs-doublet model with an additional vector boson Z′, the observed limits extend up to a Z′ mass of 3 TeV for a mass of 100 GeV for the dark matter candidate. The two-Higgs-doublet model with a dark matter particle mass of 10 GeV and an additional pseudoscalar a is excluded for masses of the a up to 520 GeV and 240 GeV for tan β = 1 and tan β = 10 respectively. Limits on the visible cross-sections are set and range from to 0.05 fb to 3.26 fb, depending on the missing transverse momentum and b-quark jet multiplicity requirements."],["dc.identifier.citation","Journal of High Energy Physics. 2021 Nov 26;2021(11):209"],["dc.identifier.doi","10.1007/JHEP11(2021)209"],["dc.identifier.pii","17250"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/97978"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/112911"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-507"],["dc.publisher","Springer Berlin Heidelberg"],["dc.relation.eissn","1029-8479"],["dc.rights.holder","The Author(s)"],["dc.subject","Dark matter"],["dc.subject","Hadron-Hadron scattering (experiments)"],["dc.title","Search for dark matter produced in association with a Standard Model Higgs boson decaying into b-quarks using the full Run 2 dataset from the ATLAS detector"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

The B mesons are reconstructed using the decay of B± into J/ψK±, with the J/ψ decaying into a pair of muons. Jets are reconstructed using the anti-kt algorithm with radius parameter R = 0.4. The measurement determines the longitudinal and transverse momentum profiles of the reconstructed B hadrons with respect to the axes of the jets to which they are geometrically associated. These distributions are measured in intervals of the jet transverse momentum, ranging from 50 GeV to above 100 GeV. The results are corrected for detector effects and compared with several Monte Carlo predictions using different parton shower and hadronisation models. The results for the longitudinal and transverse profiles provide useful inputs to improve the description of heavy-flavour fragmentation in jets."],["dc.identifier.citation","Journal of High Energy Physics. 2021 Dec 20;2021(12):131"],["dc.identifier.doi","10.1007/JHEP12(2021)131"],["dc.identifier.pii","17402"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/98896"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/112997"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-517"],["dc.relation.eissn","1029-8479"],["dc.rights.holder","The Author(s)"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject","Hadron-Hadron scattering (experiments)"],["dc.title","Measurement of b-quark fragmentation properties in jets using the decay B± → J/ψK± in pp collisions at √s = 13 TeV with the ATLAS detector"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
