• The Lorentz gauge fields in Poincare gauge theory of gravity are considered in a linear approximation. Propagators of Lorentz gauge fields are examined to show the existence of massless modes of these fields. Our consideration is restricted to the case with the condition α+2a/3=β-2a/3=γ+3a/2=0,where α, β, γand a are parameters appearing in the gravitational Lagrangian. We find that four ghost-free theories have normal modes and that each of the theories has a mode with helicity-parity 1^+ or 1^-. We also demonstrate a duality of the approximated Poincare gauge theories in this case.
