摘要：We present results for chiral extrapolations of the mass and decay constants of the rho meson.
The data sets used are the nf =2 unquenched gauge congurations generated with twisted mass
fermions by the European Twisted Mass Collaboration. We describe a calculation of three decay
constants in charmonium and explain why they are required.
