abstract = {Hadronic matrix elements involving tensor currents play an
important rôle in decays that allow to probe the
consistency of the Standard Model via precision lattice QCD
calculations. The non-singlet tensor current is a
scale-dependent (anomalous) quantity. We fully resolve its
renormalisation group (RG) running in the continuum by
carrying out a recursive finite-size scaling technique. In
this way ambiguities due to a perturbative RG running and
matching to lattice data at low energies are eliminated. We
provide the total renormalisation factor at a hadronic scale
of 233 MeV, which converts the bare current into its
RG-invariant form.Our calculation features three flavours of
O(a) improved Wilson fermions and tree-level
Symanzik-improved gauge action. We employ the (massless)
Schrödinger functional renormalisation scheme throughout
and present the first non-perturbative determination of the
Symanzik counterterm c$_{T}$ derived from an axial Ward
identity. We elaborate on various details of our
calculations, including two different renormalisation
conditions.[graphic not available: see fulltext]},
