ATLAS VH(bb/cc) Legacy Analysis
The ATLAS measurement of W/Z + Higgs production with the Higgs decaying to bottom or charm quarks, on the full Run 2 dataset, and the first direct ATLAS constraint on the charm Yukawa coupling.
Key result
|κc| < 4.2
first direct charm-Yukawa constraint
VH(bb) and VH(cc) measured together on the full Run 2 dataset. WH(bb) and ZH(bb) are each established above 5σ expected, and the charm coupling modifier is constrained directly for the first time by ATLAS. Probabilistic tagging is used throughout, from classifier training to the final fit.
