How adding zero to the complex relation between production and scattering amplitudes found by van Beveren and Rupp gives the expected real relation
M. R. Pennington, D. J. Wilson
If a hadronic production process is dominated by two body final state interactions, the amplitude for the production process can be expanded as a sum of the scattering amplitud…
Structure of the Scalars
M. R. Pennington
The PDG Tables list more scalar mesons than can fit into one quark model nonet: indeed, even more than can belong to two multiplets. Consequently, some of these must be states beyo…
Location, correlation, radiation: where is the , what is its structure and what is its coupling to photons?
M. R. Pennington
Scalar mesons are a key expression of the infrared regime of QCD. The lightest of these is the . Now that its pole in the complex energy plane has been precisely located, we can…
Extracting the condensate for light quarks beyond the chiral limit in models of QCD
R. Williams, C. S. Fischer, M. R. Pennington
It has recently been suggested \cite{Chang:2006bm} that a reliable and unambiguous definition of the non-perturbative massive quark condensate could be provided by considering a no…
Quark Condensates: Flavour Dependence
R. Williams, C. S. Fischer, M. R. Pennington
We determine the q-bar q condensate for quark masses from zero up to that of the strange quark within a phenomenologically successful modelling of continuum QCD by solving the quar…
Aspects of quark mass generation on a torus
C. S. Fischer, M. R. Pennington
In this talk we report on recent results for the quark propagator on a compact manifold. The corresponding Dyson-Schwinger equations on a torus are solved on volumes similar to the…
