Description
In this contribution, updated results from simulations by the
European Twisted Mass Collaboration at the physical point using
Wilson twisted mass fermions with a clover term are presented. We
discuss results for the pseudoscalar decay constants $f_K$, $f_D$
and $f_{D_s}$ and the corresponding masses. In addition, we provide
evidence for a largely reduced flavour symmetry breaking in the
presence of a clover term.
