We present an update on our ongoing study on the nature of the bulk transition observed at strong coupling in the SU(3) gauge theory with N_f = 12 flavors in the fundamental representation. We show evidence that there is a first order chiral symmetry breaking bulk transition separating a region at weak coupling where chiral symmetry is restored from a region at strong coupling where chiral symmetry is broken. We also discuss hints of a separate partial restoration of U_A(1) at weaker coupling. The results are in agreement with restoration of conformality in non abelian gauge theories as the number of flavors is increased.

    Numerical study of partition function zeros in 12-flavor lattice QCD finds strong evidence for first-order transitions at m_q=0.02 with scaling d=3.98(6) and suggests critical mass m_q^c approximately 0.05 where the t...
