| Popis: | 37th International Symposium on Lattice Field Theory, Lattice 2019, Wuhan, China, 16 Jun 2019 - 22 Jun 2019; Proceedings of Science / International School for Advanced Studies (LATTICE2019), 212 (2020). doi:10.22323/1.363.0212 We present our progress in the non-perturbative $O(a)$ improvement and renormalization of tensor currents in three-flavor lattice QCD with Wilson-clover fermions and tree-level Symanzik improved gauge action. The mass-independent $O(a)$ improvement factor of tensor currents isdetermined via a Ward identity approach, and their renormalization 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 < 0.1 fm, relevant for phenomenological large-volume lattice QCD applications.
