Parton distributions in the SMEFT from high-energy Drell-Yan tails
/ Greljo, Admir (U. Bern, AEC ; CERN) ; Iranipour, Shayan (Cambridge U., DAMTP) ; Kassabov, Zahari (Cambridge U., DAMTP) ; Madigan, Maeve (Cambridge U., DAMTP) ; Moore, James (Cambridge U., DAMTP) ; Rojo, Juan (Vrije U., Amsterdam ; NIKHEF, Amsterdam) ; Ubiali, Maria (Cambridge U., DAMTP) ; Voisey, Cameron (Cambridge U.)
The high-energy tails of charged- and neutral-current Drell-Yan processes provide important constraints on the light quark and anti-quark parton distribution functions (PDFs) in the large-x region. [...]

Hadronic light-by-light contribution to $(g-2)_\mu$ from lattice QCD: a complete calculation
/ Chao, En-Hung (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA) ; Hudspith, Renwick J. (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA) ; Gérardin, Antoine (Marseille, CPT) ; Green, Jeremy R. (CERN) ; Meyer, Harvey B. (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA ; Helmholtz Inst., Mainz ; Darmstadt, GSI) ; Ottnad, Konstantin (Mainz U., Inst. Kernphys. ; U. Mainz, PRISMA)
We compute the hadronic light-by-light scattering contribution to the muon $g-2$ from the up, down, and strange-quark sector directly using lattice QCD. [...]

Double-crystal measurements at the CERN SPS
/ Scandale, W. (CERN ; Imperial Coll., London ; INFN, Rome) ; Arduini, G. (CERN) ; Cerutti, F. (CERN) ; D'Andrea, M. (CERN ; Padua U.) ; Esposito, L.S. (CERN) ; Garattini, M. (CERN ; Imperial Coll., London) ; Gilardoni, S. (CERN) ; Mirarchi, D. (CERN ; Manchester U.) ; Montesano, S. (CERN) ; Natochii, A. (CERN ; IJCLab, Orsay ; Taras Shevchenko U.) et al.
The UA9 setup, installed in the Super Proton Synchrotron (SPS) at CERN, was exploited for a proof of principle of the double-crystal scenario, proposed to measure the electric and the magnetic moments of short-lived baryons in a high-energy hadron collider, such as the Large Hadron Collider (LHC).
