  Many evidences from lattice simulations support the idea that SU(2) with two
Dirac flavors in the adjoint representation (also called Minimal Walking
Technicolor) is IR conformal. A possible way to see this is through the
behavior of the spectrum of the mass-deformed theory. When fermions are
massive, a mass-gap is generated and the theory is confined. IR-conformality is
recovered in the chiral limit: masses of particles vanish in the chiral limit,
while their ratios stay finite. In order to trust this analysis one has to
relay on the infinite volume extrapolation. We will discuss the finite volume
effects on the mesonic spectrum, investigated by varying the size of the
lattice and by changing the boundary conditions for the fields.
