Yang-Mills glueball masses from spectral reconstruction
Jan M. Pawlowski, Coralie S. Schneider, Jonas Turnwald +2
We compute masses of the two lightest glueballs from spectral reconstructions of timelike interaction channels of the four-gluon vertex in Landau gauge Yang-Mills theory. The Eucli…
On the quark spectral function in QCD
Jan Horak, Jan M. Pawlowski, Nicolas Wink
We calculate the spectral function of light quark flavours in 2+1 flavour vacuum QCD in the isospin-symmetric approximation. We employ spectral Dyson-Schwinger equations and comput…
Local Discontinuous Galerkin for the Functional Renormalisation Group
Friederike Ihssen, Jan M. Pawlowski, Franz R. Sattler +1
We apply the Local Discontinuous Galerkin discretisation to flow equations of the O(N)-model in the Local Potential Approximation. The improved stability is directly observed by so…
Renormalised spectral flows
Jens Braun, Yong-rui Chen, Wei-jie Fu +11
We derive renormalised finite functional flow equations for quantum field theories in real and imaginary time that incorporate scale transformations of the renormalisation conditio…
On Gauge Consistency In Gauge-Fixed Yang-Mills Theory
Jan M. Pawlowski, Coralie S. Schneider, Nicolas Wink
We investigate BRST invariance in Landau gauge Yang-Mills theory with functional methods. To that end, we solve the coupled system of functional renormalisation group equations for…
On the complex structure of Yang-Mills theory
Jan Horak, Jan M. Pawlowski, Nicolas Wink
We consider the coupled set of spectral Dyson-Schwinger equations in Yang-Mills theory for ghost and gluon propagators, which gives us access to the ghost and gluon spectral functi…
