Journal ArticleDOI
Chiral Symmetry and Charmonium Decays to Two Pseudoscalars
Johan Bijnens,Ilaria Jemos +1 more
TL;DR: In this article, the authors apply hard conjecture chiral perturbation theory to charmonium and show that the leading chiral logarithm is absent for all singlet states of spin zero and two.
Journal ArticleDOI
Short-distance constraints for HLbL in muon g-2
TL;DR: In this article , the authors focus on the region where the three loop virtualities are large and show how a precise Operator Product Expansion can be applied in that region, even when the fourth photon leg is soft.
Proceedings ArticleDOI
$K_{l4}$ at two-loops and CHPT predictions for $\pi\pi$-scattering
TL;DR: In this article, the results from two-loop calculations of masses, decay-constants, vacuum-expectation-values and the $K_{\ell4}$ formfactors in three-flavour Chiral Perturbation Theory (CHPT) were presented.
Obtaining K from off-shell K 7r amplitudes
TL;DR: In this paper, the off-shell K ~ ~ transition amplitudes were defined and used to extract information for on-shell k ~ ~'~" amplitudes within Chiral Perturbation Theory.
