Description
We present our progress on the non-perturbative $\mathrm{O}(a)$ improvement and renormalization of tensor currents in three flavor lattice QCD with Wilson-clover fermions and tree-level Symanzik improved gauge action. While the $\mathrm{O}(a)$ improvement factor of the tensor currents is determined via a Ward identity approach, their RG group running is calculated via recursive finite-size scaling techniques, both implemented within the Schrödinger functional framework. We also address the matching factor between bare and renormalization group invariant currents for a range of lattice spacings relevant for applications from large-volume simulations.
