We investigate a variant of hypercubic gauge link smearing where the SU(3) projection is replaced with a normalization to the corresponding unitary group. This smearing is differentiable and thus suitable for use in dynamical fermion simulations using molecular dynamics type algorithms. We show that this smearing is as efficient as projected hypercubic smearing in removing ultraviolet noise from the gauge fields. We test the normalized hypercubic smearing in dynamical improved (clover) Wilson and valence overlap simulations.

Investigating SU(3) with Nf=8 fundamental fermions at strong renormalized coupling
Finite-size scaling of lattice data favors a merged fixed point governing the strong-to-weak coupling transition in SU(3) with eight fundamental flavors, suggesting this system sits at the opening of the conformal window.

Comparison of a pseudoscalar meson form factor in QCD with 3, 4, and 5 colors
Measurements of the pseudoscalar meson vector form factor in SU(3), SU(4), and SU(5) lattice QCD show that its shape is nearly independent of Nc and roughly follows vector meson dominance.
