DOI: 10.1007/jhep10(2018)141
Abstract: A bstractThe 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. Although this crucial input quantity is,… read more here.

DOI: 10.1038/s42005-024-01774-8
Abstract: Weakly interacting massive particles (WIMPs) may interact with a virtual pion that is exchanged between nucleons. This interaction channel is important to consider in models where the spin-independent isoscalar channel is suppressed. Using data from… read more here.
