This method relies on the assumption that the tree-level Higgs-top Yukawa coupling strength is the same for on-shell and off-shell Higgs boson production processes, thereby avoiding any assumptions about the relationship between on-shell and off-shell gluon fusion Higgs production rates, which were central to previous measurements. The result is based on up to 140 fb$^{−1}$ of proton–proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The observed (expected) 95\% confidence level upper limit on $Γ_H$ is 450 MeV (75 MeV). Additionally, considering the constraint on the Higgs-top Yukawa coupling from loop-induced Higgs boson production and decay processes further yields an observed (expected) upper limit of 160 MeV (55 MeV).}, cin = {ATLAS}, ddc = {530}, cid = {I:(DE-H253)ATLAS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF4-611) / DFG project G:(GEPRIS)469666862 - Präzisionstests des Standardmodells unter der Verwendung von geboosteten W/Z-Bosonen am Large Hadron Collider (469666862) / REALDARK - REAL-time discovery strategies for DARK matter and dark sector signals at the ATLAS detector with Run-3 LHC data (101002463) / DITTO - Comprehensive search for new phenomena in the dilepton spectrum at the LHC (101089007)}, pid = {G:(DE-HGF)POF4-611 / G:(GEPRIS)469666862 / G:(EU-Grant)101002463 / G:(EU-Grant)101089007}, experiment = {EXP:(DE-H253)LHC-Exp-ATLAS-20150101}, typ = {PUB:(DE-HGF)16}, eprint = {2407.10631}, howpublished = {arXiv:2407.10631}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:2407.10631;\%\%$}, doi = {10.1016/j.physletb.2025.139277}, url = {https://bib-pubdb1.desy.de/record/637037}, }
