Electromagnetic, weak, and strong interactions of light mesons
P. Maris
The ladder-rainbow truncation of the set of Dyson-Schwinger equations is used to study a variety of electroweak and strong processes involving light mesons. The parameters in the e…
Mesons as Bound States of Confined Quarks: Zero and Finite Temperature
Pieter Maris, Peter C. Tandy
We survey recent work on the properties and decays of mesons as bound states of confined quarks at both zero and finite temperature. The framework for these investigations is the s…
Calculating the critical exponents of the chiral phase transition
P. Maris
We calculate the critical exponents of the chiral phase transition at nonzero temperature using the thermal and chiral susceptibilities. We show that within a class of confining Dy…
QCD bound states and their response to extremes of temperature and density
Pieter Maris, Craig D. Roberts
We describe the application of Dyson-Schwinger equations to the calculation of hadron observables. The studies at zero temperature (T) and quark chemical potential (mu) provide a s…
Leptonic and semileptonic decays of heavy mesons
C. D. Roberts, M. A. Ivanov, Yu. L. Kalinovsky +1
A heavy-quark limit of the Dyson-Schwinger equations is introduced and used in an exploratory study of leptonic and semileptonic decays of heavy mesons. The application of this fra…
Differences between heavy and light quarks
P. Maris, C. D. Roberts
The quark Dyson-Schwinger equation shows that there are distinct differences between light and heavy quarks. The dynamical mass function of the light quarks is characterised by a s…
