Light by light scattering at a low energy collider -or- What to do while waiting for that rare kaon decay event
M. R. Pennington
Two photon processes are a wonderful by-product of an collider at any energy. Two photon reactions probe the very structure of matter. A machine operating below 2 GeV has…
In the debris of hadron interactions lies the beauty of QCD (part II)
M. R. Pennington
Recent progress in understanding the strong physics regime of QCD is described. The role played by condensates, particularly , in breaking chiral symmetry and generat…

The Lightest Strange Scalar Resonance
S. N. Cherry, M. R. Pennington
I present the results of a recent calculation to determine the number of strange scalar resonances below 1.8 GeV based on the analytic properties of the experimental pi K scatterin…
Analytic Form of the One-loop Vertex and of the Two-loop Fermion Propagator in 3-Dimensional Massless QED
A. Bashir, A. Kizilersu, M. R. Pennington
We evaluate the analytic expression for the one-loop fermion-boson vertex in massless QED3 in an arbitrary covariant gauge. The result is written in terms of elementary functions o…
Riddle of the scalars: where is the sigma?
M. R. Pennington
The riddle of the sigma is recast in a way that tries to differentiate fact from fiction as a basis for future/further discussion. By doing this, it is hoped that the role of the s…
