Phys Rev Lett . 2025 Jan; 133(26):261803. PMID: 39878999
Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are...

Phys Rev Lett . 2025 Jan; 133(25):252301. PMID: 39752696
High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the...

Phys Rev Lett . 2024 Nov; 133(16):161804. PMID: 39485985
A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy...
