A no-go theorem for non-standard explanations of the CP asymmetry
Vincenzo Cirigliano, Andreas Crivellin, Martin Hoferichter
The CP asymmetry in , as measured by the BaBar collaboration, differs from the Standard Model prediction by . Most non-standard interactions do not allow for th…
Hadronic light-by-light contribution to : a dispersive approach
Gilberto Colangelo, Martin Hoferichter, Massimiliano Procura +1
After a brief introduction on ongoing experimental and theoretical activities on , we report on recent progress in approaching the calculation of the hadronic light-by-lig…
Radiative resonance couplings in
Martin Hoferichter, Bastian Kubis, Marvin Zanke
Studies of the reaction , in the context of the ongoing Primakoff program of the COMPASS experiment at CERN, give access to the radiative couplings of the and $ρ_…
Improved limits for Higgs-portal dark matter from LHC searches
Martin Hoferichter, Philipp Klos, Javier Menéndez +1
Searches for invisible Higgs decays at the Large Hadron Collider constrain dark matter Higgs-portal models, where dark matter interacts with the Standard Model fields via the Higgs…
Extracting the sigma-term from low-energy pion-nucleon scattering
Jacobo Ruiz de Elvira, Martin Hoferichter, Bastian Kubis +1
We present an extraction of the pion-nucleon () scattering lengths from low-energy scattering, by fitting a representation based on Roy-Steiner equations to the low-energy…
Dispersion relation for hadronic light-by-light scattering: two-pion contributions
Gilberto Colangelo, Martin Hoferichter, Massimiliano Procura +1
In this third paper of a series dedicated to a dispersive treatment of the hadronic light-by-light (HLbL) tensor, we derive a partial-wave formulation for two-pion intermediate sta…
