Width effects of broad new resonances in loop observables and application to
Andreas Crivellin, Martin Hoferichter
In the phenomenology of strong interactions most physical states acquire a substantial width, and thus can only be defined in a model-independent way by pole positions and residues…
Chiral extrapolation of hadronic vacuum polarization and isospin-breaking corrections
Martin Hoferichter, Gilberto Colangelo, Bai-Long Hoid +4
By far the biggest contribution to hadronic vacuum polarization (HVP) arises from the two-pion channel. Its quark-mass dependence can be evaluated by combining dispersion relations…
Scrutinizing CKM unitarity with a new measurement of the branching fraction
Vincenzo Cirigliano, Andreas Crivellin, Martin Hoferichter +1
Precision tests of first-row unitarity of the Cabibbo-Kobayashi-Maskawa matrix currently display two intriguing tensions, both at the level. First, combining determinations of…
Isospin-breaking effects in the two-pion contribution to hadronic vacuum polarization
Gilberto Colangelo, Martin Hoferichter, Bastian Kubis +1
Isospin-breaking (IB) effects in the two-pion contribution to hadronic vacuum polarization (HVP) can be resonantly enhanced, if related to the interference of the and $ω(7…
The Anomalous Magnetic Moment of the Muon: Beyond the Standard Model via Chiral Enhancement
Andreas Crivellin, Martin Hoferichter
The anomalous magnetic moment of the muon displays a tension with the Standard-Model prediction, if data are used for hadronic vacuum polarization…
Radiative corrections to the forward-backward asymmetry in
Gilberto Colangelo, Martin Hoferichter, Joachim Monnard +1
We present a calculation of the -odd radiative corrections to in a dispersive formalism, concentrating on the leading pion-pole contribution in the virtual bo…
