Pion Polarizabilities from Analysis
Ling-Yun Dai, Michael R. Pennington
We present results for pion polarizabilities predicted using dispersion relations from our earlier Amplitude Analysis of world data on two photon production of meson pairs. The hel…
Application of the Veneziano Model in Charmonium Dalitz Plot Analysis
Adam P. Szczepaniak, M. R. Pennington
We adapt the Veneziano model to the analysis of vector charmonium decays. Starting from a set of covariant Veneziano terms we show how to construct partial waves amplitudes that re…
On Radiative , Decays
Fulvia De Fazio, M. R. Pennington
We use QCD sum-rules to study the decays and , obtaining and ${\cal B}(ϕ\to η^\prime γ)=(1.18 \pm 0.4) 10^{-4}…
Numerical cancellation of photon quadratic divergence in the study of the Schwinger-Dyson equations in Strong Coupling QED
J. C. R. Bloch, M. R. Pennington
The behaviour of the photon renormalization function in strong coupling QED has been recently studied by Kondo, Mino and Nakatani. We find that the sharp decrease in its behaviour…
