Near conformal dynamics is employed in different extensions of the standard
model of particle interactions as well as in cosmology. Many of its interesting
properties are either conjectured or determined using model computations. We
introduce a relevant four dimensional gauge theory template allowing us to
investigate such dynamics perturbatively. The gauge theory we consider is
quantum chromodynamics with the addition of a meson-like scalar degree of
freedom as well as an adjoint Weyl fermion.
At the two-loop level, and in the Veneziano limit, we firmly establish the
existence of several fixed points of which one is all directions stable in the
infrared. An interesting feature of the model is that this fixed point is lost,
within the perturbatively trustable regime, by merging with another fixed point
when varying the number of quark flavors. We show the emergence of the Miransky
scaling and determine its properties. We are also able to determine the walking
region of the theory which turns out to be, at large number of colors, about
12% of the conformal window. Furthermore, we determine highly relevant
quantities for near conformal dynamics such as the anomalous dimension of the
fermion masses.Comment: 17 pages, 8 figure
