Apparent convergence in functional glueball calculations
Markus Q. Huber, Christian S. Fischer, Hèlios Sanchis-Alepuz
We scrutinize the determination of glueball masses in pure Yang-Mills theory from functional equations, i.e. Dyson-Schwinger and Bethe-Salpeter equations. We survey the state-of-th…
Glueballs from Dyson-Schwinger and Bethe-Salpeter equations
Markus Q. Huber, Christian S. Fischer, Hèlios Sanchis-Alepuz
The quenched spectrum of glueballs with positive charge parity is calculated from two-body bound state equations. As input, a self-contained solution for the primitively divergent…
How to determine the branch points of correlation functions in Euclidean space II: Three-point functions
Markus Q. Huber, Wolfgang J. Kern, Reinhard Alkofer
The analytic structure of elementary correlation functions of a quantum field is relevant for the calculation of masses of bound states and their time-like properties in general. I…
The analytic structure of three-point functions from contour deformations
Markus Q. Huber, Wolfgang J. Kern, Reinhard Alkofer
We explore the analytic structure of three-point functions using contour deformations. This method allows continuing calculations analytically from the spacelike to the timelike re…
Glueballs from bound state equations
Markus Q. Huber, Christian S. Fischer, Helios Sanchis-Alepuz
Glueballs are bound states in the spectrum of quantum chromodynamics which consist only of gluons. They belong to the group of exotic hadrons which are widely studied experimentall…
Quenched glueballs in the DSE/BSE framework
Markus Q. Huber, Christian S. Fischer, Hèlios Sanchis-Alepuz
The spectrum of glueballs with quantum numbers is calculated in quenched quantum chromodynamics from bound state equations. The…
