Projections for Key Measurements in Heavy Flavour Physics
Precision studies of flavour-changing processes involving quarks and leptons provide a number of ways to improve knowledge of the Standard Model and search for physics beyond it. [...]

Measurements and interpretation of the Higgs boson differential and production mode cross sections in the $H \rightarrow ZZ^* \rightarrow 4\ell$ channel at $\sqrt{s}=13.6$ TeV with the ATLAS detector
Higgs boson production cross-sections are measured in the $H\rightarrow~ZZ^\ast\rightarrow~4\ell$ decay channel based on 56 fb$^{-1}$ of proton-proton collision data produced at the Large Hadron Collider at a centre-of-mass energy of 13.6 TeV and recorded by the ATLAS detector in 2022 and 2023.

Measurements of $Z\gamma$ differential cross sections and search for neutral triple gauge couplings in $pp$ collisions at $\sqrt{s} =$ 13 TeV with the ATLAS detector
The measurements of the cross sections for $Z\gamma$ production and the search for neutral triple gauge couplings (nTGC) through $ZZ\gamma$ or $\gamma^* Z\gamma$ vertices are presented, using the full Run2 proton-proton dataset of 140 fb$^{-1}$ produced by the LHC at $\sqrt{s}$ = 13 TeV and collected by the ATLAS detector.

Heavy Flavour results from ATLAS / Warburton, Andreas (McGill University, (CA))
Heavy flavour production cross sections and lifetimes in hadron colliders inform and challenge perturbative and non-perturbative quantum chromodynamics (QCD) determinations, while providing sensitivity to physics beyond the Standard Model. [...]
