Meson spectroscopy and properties using dyson-schwinger equations
TLDR
In this paper, the authors studied pseudoscalar and scalar mesons using a practical and symmetry preserving truncation of QCD's Dyson-Schwinger equations.Abstract:
We study pseudoscalar and scalar mesons using a practical and symmetry preserving truncation of QCD's Dyson-Schwinger equations. We investigate and compare properties of ground and radially excited meson states. In addition to exact results for radial meson excitations we also present results for meson masses and decay constants from the chiral limit up to the charm-quark mass, e.g., the mass of the χc0(2P) meson.read more

Hadron Properties and Dyson-Schwinger Equations
TL;DR: An overview of the theory and phenomenology of hadrons and QCD is provided from a Dyson-Schwinger equation viewpoint in this article, followed by a discussion of the definition and realization of light quark confinement, the nonperturbative nature of the running mass in QCD and inferences from the gap equation relating to the radius of convergence for expansions of observables in the current quark mass are described.

B-meson to light-meson transition form factors.
TL;DR: In this article, a comprehensive set of results for B-meson heavy-to-light transition form factors calculated using a truncation of, and expression for, the transition amplitudes in which all elements are motivated by the study of Dyson-Schwinger equations in QCD is reported.

Schwinger Functions and Light-Quark Bound States
TL;DR: In this paper, the applicability and viability of methods to obtain knowledge about bound states from information provided solely in Euclidean space are examined, and it is shown that such methods are not competitive when an unambiguous analytic continuation of even a single Schwinger function to complex momenta is available.

Baryons in a relativized quark model with chromodynamics
Simon Capstick,Nathan Isgur +1 more
TL;DR: The three quark system is studied in a relativized version of the quark potential model with chromodynamics and the spectrum of baryons is described with parameters consistent with those of an analogous study of meson spectroscopy.

The Infrared Behavior of QCD Green's Functions - Confinement, Dynamical Symmetry Breaking, and Hadrons as Relativistic Bound States
TL;DR: In this paper, a review of recent studies of QCD Green's functions and their applications in hadronic physics are reviewed. But the issues of gauge fixing, BRS invariance and positivity are briefly discussed, and evidence for the violation of positivity by quarks and transverse gluons in the covariant gauge is collected.
