The Brief Life of a Hadron: QCD unquenched
Michael R. Pennington
Once upon a time, the picture of hadrons was of mesons made of a quark and an antiquark, and baryons of three quarks. Though hadrons heavier than the ground states inevitably decay…
Dynamical mass generation in unquenched QED using the Dyson--Schwinger equations
Ayse Kizilersu, Michael R. Pennington, Tom Sizer +2
We present a comprehensive numerical study of dynamical mass generation for unquenched QED in four dimensions, in the absence of four-fermion interactions, using the Dyson--Schwing…
Comprehensive Amplitude Analysis of and below 1.5 GeV
Ling-Yun Dai, Michael R. Pennington
In this paper we perform an amplitude analysis of essentially all published pion and kaon pair production data from two photon collisions below 1.5 GeV. This includes all the high…
Two photon couplings of the lightest isoscalars from BELLE data
Ling-Yun Dai, M. R. Pennington
Amplitude Analysis of two photon production of and , using S-matrix constraints and fitting all available data, including the latest precision results from Bel…
