Spontaneous BRST symmetry breaking in infrared QCD
Angelo Raffaele Fazio, Adam Smetana
We present a novel proposal for the effective Lagrangian of the low-energy Yang--Mills quantum field theory. The proposed effective Lagrangian exhibits the spontaneous BRST symmetr…

Ghost condensates in Yang-Mills theories in nonlinear gauges
A. R. Fazio, V. E. R. Lemes, M. Picariello +2
Ghost condensates of dimension two are analysed in a class of nonlinear gauges in pure Yang-Mills theories. These condensates are related to the breaking of the SL(2,R) symmetry, p…
