1. Nature of the Y(4260): A light-quark perspective / Chen, Yun-Hua ; Dai, Ling-Yun ; Guo, Feng-Kun ; Kubis, Bastian
The Y(4260) has been one of the most puzzling pieces among the so-called XYZ states. [...]

2. Nucleon Matrix Elements of the Antisymmetric Quark Tensor / Hoferichter, Martin ; Kubis, Bastian ; Ruiz de Elvira, Jacobo ; Stoffer, Peter
If physics beyond the standard model enters well above the electroweak scale, its low-energy effects are described by standard model effective field theory. [...]

3. A new parametrization for the scalar pion form factors / Ropertz, Stefan ; Hanhart, Christoph ; Kubis, Bastian
We derive a new parametrization for the scalar pion form factors that allows us to analyze data over a large energy range via the inclusion of resonances, and at the same time to ensure consistency with the high-accuracy dispersive representations available at low energies. [...]

5. Dispersion relation for hadronic light-by-light scattering: pion pole / Hoferichter, Martin ; Hoid, Bai-Long ; Kubis, Bastian ; Leupold, Stefan ; et al
The pion-pole contribution to hadronic light-by-light scattering in the anomalous magnetic moment of the muon ( g − 2) μ is fully determined by the doubly-virtual pion transition form factor. [...]

6. Pion-Pole Contribution to Hadronic Light-By-Light Scattering in the Anomalous Magnetic Moment of the Muon / Hoferichter, Martin ; Hoid, Bai-Long ; Kubis, Bastian ; Leupold, Stefan ; et al
The π0 pole constitutes the lowest-lying singularity of the hadronic light-by-light (HLBL) tensor, and thus, it provides the leading contribution in a dispersive approach to HLBL scattering in the anomalous magnetic moment of the muon (g2)μ. [...]

9. Remarks on the pion–nucleon σ -term / Hoferichter, Martin ; Ruiz de Elvira, Jacobo ; Kubis, Bastian ; Meißner, Ulf-G.
The pion–nucleon σ -term can be stringently constrained by the combination of analyticity, unitarity, and crossing symmetry with phenomenological information on the pion–nucleon scattering lengths. [...]
