The running coupling from gluon and ghost propagators in the Landau gauge: Yang-Mills theories with adjoint fermions

Understand

Non-Abelian gauge theories with fermions transforming in the adjoint representation of the gauge group (AdjQCD) are a fundamental ingredient of many models that describe the physics beyond the Standard Model.

• Two relevant examples are N=1 Supersymmetric Yang-Mills (SYM) theory and Minimal Walking Technicolor, which are gauge theories coupled to one adjoint Majorana and two adjoint Dirac fermions, respectively.
• While confinement is a property of N=1 SYM, Minimal Walking Technicolor is expected to be infrared conformal.
• We study the propagators of ghost and gluon fields in the Landau gauge to compute the running coupling in the MiniMom scheme.
