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…
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…
Gluon condensates and effective gluon mass
Jan Horak, Friederike Ihssen, Joannis Papavassiliou +3
Lattice simulations along with studies in continuum QCD indicate that non-perturbative quantum fluctuations lead to an infrared regularisation of the gluon propagator in covariant…
