      abstract     = {We describe a fully generic implementation of two-body
                      partial decay widths at the full one-loop level in the SARAH
                      and SPheno framework compatible with most supported models.
                      It incorporates fermionic decays to a fermion and a scalar
                      or a gauge boson as well as scalar decays into two fermions,
                      two gauge bosons, two scalars or a scalar and a gauge boson.
                      We present the relevant generic expressions for virtual and
                      real corrections. Whereas wavefunction corrections are
                      determined from on-shell conditions, the parameters of the
                      underlying model are by default renormalised in a DR (or MS)
                      scheme. However, the user can also define model-specific
                      counter-terms. As an example we discuss the renormalisation
                      of the electric charge in the Thomson limit for top-quark
                      decays in the standard model. One-loop induced decays are
                      also supported. The framework additionally allows the
                      addition of mass and mixing corrections induced at higher
                      orders for the involved external states. We explain our
                      procedure to cancel infra-red divergences for such cases,
                      which is achieved through an infra-red counter-term taking
                      into account corrected Goldstone boson vertices. We compare
                      our results for sfermion, gluino and Higgs decays in the
                      minimal supersymmetric standard model (MSSM) against the
                      public codes SFOLD, FVSFOLD and HFOLD and explain observed
                      differences. Radiative induced gluino and neutralino decays
                      are compared against the original implementation in SPheno
                      in the MSSM. We exactly reproduce the results of the code
                      CNNDecays for decays of neutralinos and charginos in
                      R-parity violating models. The new version SARAH 4.11.0 by
                      default includes the calculation of two-body decay widths at
                      the full one-loop level. Current limitations for certain
                      model classes are described.},
