5. Resonances and QCD

Raul Briceno (Jefferson Lab)

2/1/17, 11:00 AM

The non-perturbative nature of quantum chromodynamics (QCD) has historically left a gap in our understanding of the connection between the fundamental theory of the strong interactions and the rich structure of experimentally observed phenomena. For the simplest properties of stable hadrons, this is now circumvented with the use of lattice QCD (LQCD). In this talk I discuss a path towards a...

53. Investigation of the Hadronic Decay η→π+π−π0 with CLAS

Mr Daniel Lersch (Juelich Research Center)

2/1/17, 11:25 AM

The amplitude of the isospin violating decay $\eta \to {\pi }^{+}{\pi }^{-}{\pi }^0$ is sensitive to the ratio Q of the light quark masses. This decay amplitude is accessible via a Dalitz Plot analysis, resulting in a set of parameters which can be compared to theoretical predictions. The latest measurements on those parameters have been performed by the KLOE and the WASA-at-COSY experiment. The...

22. Test Fundamental Symmetries via Precision Measurements of π0, η and η′ Decays

Prof. Liping Gan (University of North Carolina Wilmington)

2/1/17, 11:50 AM

Light neutral meson decays provide a unique laboratory to test fundamental symmetries in physics. A comprehensive Primakoff experimental program at Jefferson Laboratory (JLab) is aimed at gathering high precision measurements on the two-photon decay widths and the transition form factors at low four-momentum transfer squares for ${\pi }^0$, $\eta$ and ${\eta }^{\prime }$ via the Primakoff effect. The...

96. Strong interaction with strangeness in the low energy regime: strange atoms, resonances, nuclei

Dr Johann Marton (Stefan Meyer Institute, Austrian Academy of Sciences)

2/1/17, 12:15 PM

There is substantial progress in the understanding of the strong interaction involving strange quarks. However, many aspects of the interactions of antikaons with nucleons and nuclei are still open which are also related to the open question about the role of strangeness in neutron stars. The K- nucleon interaction is strongly attractive at low energies in agreement to theory. This attraction...
