Comparing phenomenological estimates of dilepton decays of pseudoscalar mesons with lattice QCD
Bai-Long Hoid, Martin Hoferichter, Jacobo Ruiz de Elvira
Dilepton decays of pseudoscalar mesons have been drawing particular interest, thanks to their sensitivity to both the QCD dynamics at low energy and also signals beyond the Standar…
Workshop summary -- Kaons@CERN 2023
G. Anzivino, S. Arguedas Cuendis, V. Bernard +60
Kaon physics is at a turning point -- while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscap…
Improved Standard-Model prediction for
Martin Hoferichter, Bai-Long Hoid, Jacobo Ruiz de Elvira
We present a comprehensive calculation of the form factor in dispersion theory, using input from the leptonic decays , $K_L\to \ell_1^+\ell_1^-\…
Isospin-breaking effects in the three-pion contribution to hadronic vacuum polarization
Martin Hoferichter, Bai-Long Hoid, Bastian Kubis +1
Isospin-breaking (IB) effects are required for an evaluation of hadronic vacuum polarization at subpercent precision. While the dominant contributions arise from the $e^+e^-\toπ^+π…
A phenomenological estimate of isospin breaking in hadronic vacuum polarization
Martin Hoferichter, Gilberto Colangelo, Bai-Long Hoid +5
Puzzles in the determination of the hadronic-vacuum-polarization contribution currently impede a conclusive interpretation of the precision measurement of the anomalous magnetic mo…
