Light and shadow among QCD and QED

16 nov. 2016, 14:00 → 17 nov. 2016, 13:00 Europe/Zurich

Montpellier, France

In the framework of the topic "QCD at low energy" of the GDR "QCD", this workshop aims to discuss about progresses in the theoretical estimates of radiative corrections to hadronic quantities, the treatment by experiments of soft photons in the final state of hadronic decays and the computation of QCD contributions to leptonic quantities.
