Exact Lattice Identities and Continuum-Limit Dyson--Schwinger Equations for Yang-Mills Theory
Arpan Chatterjee, Marco Frasca, Anish Ghoshal +1
Starting from SU(N) on the lattice, we give a rigorous derivation of the Dyson--Schwinger equations in the continuum limit. We formulate the Dyson--Schwinger identities for the lat…
Zero mass as a Borel structure
Rein Saar, Stefan Groote
The Lorentz group LorSO has two point fixgroups, namely SO for time-like translations and SO for light-like translations. However, for lig…
Finite temperature QCD crossover at non-zero chemical potential: A Dyson-Schwinger approach
Arpan Chatterjee, Marco Frasca, Anish Ghoshal +1
We study QCD at finite temperature and non-zero chemical potential to derive the critical temperature at the chiral phase transition (crossover). We solve a set of Dyson--Schwinger…
Non-perturbative quantum Yang--Mills at finite temperature beyond lattice: a Dyson--Schwinger approach
Marco Frasca, Anish Ghoshal, Stefan Groote
Using a Dyson--Schwinger approach, we perform an analysis of the non-trivial ground state of thermal Yang--Mills theory in the non-perturbative regime where chiral symmetry…
Dynamical generation of electroweak scale from the conformal sector: A strongly coupled Higgs via the Dyson--Schwinger approach
Arpan Chatterjee, Marco Frasca, Anish Ghoshal +1
We propose a novel pathway to generate the electroweak (EW) scale via non-perturbative dynamics of a conformally invariant scalar sector at the classical level. We provide a method…
Some exact Green function solutions for non-linear classical field theories
Marco Frasca, Stefan Groote
We consider some non-linear non-homogeneous partial differential equations (PDEs) and derive their exact Green function solution as a functional Taylor expansion in powers of the s…
