Recent Developments in the Bethe-Salpeter Description of Light Mesons
Peter Watson
Results for the light meson mass spectrum from a Bethe-Salpeter approach are presented. The results obtained in the standard framework are Poincaré covariant and compare favourably…
Bethe-Salpeter Meson Masses Beyond Ladder Approximation
P. Watson, W. Cassing, P. C. Tandy
The effect of quark-gluon vertex dressing on the ground state masses of the u/d-quark pseudoscalar, vector and axialvector mesons is considered with the Dyson-Schwinger equations.…
A Limit on Short-range Modifications to Gravity
P. J. S. Watson
There has been considerable interest in providing new limits on the short range behaviour of gravity, or, in general, anomalous short-range interactions. In this note we show that…
Unquenching the Quark-Antiquark Green's Function
Peter Watson, Wolfgang Cassing
We propose a nonperturbative resummation scheme for the four-point connected quark-antiquark Green's function that shows how the Bethe-Salpeter equation may be `unquenched' w…
