Complete dispersive evaluation of the hadronic light-by-light contribution to muon
Martin Hoferichter, Peter Stoffer, Maximilian Zillinger
Hadronic light-by-light (HLbL) scattering defines one of the critical contributions in the Standard-Model prediction of the anomalous magnetic moment of the muon. In this Letter, w…
Dispersion relation for hadronic light-by-light scattering: subleading contributions
Martin Hoferichter, Peter Stoffer, Maximilian Zillinger
In this work, we present an evaluation of subleading effects in the hadronic light-by-light contribution to the anomalous magnetic moment of the muon. Using a recently derived opti…
An optimized basis for hadronic light-by-light scattering
Martin Hoferichter, Peter Stoffer, Maximilian Zillinger
We present a new basis for the hadronic light-by-light (HLbL) tensor that is optimized for the evaluation of narrow-resonance contributions to HLbL scattering in the anomalous magn…
