摘要:We present an update of the results for pion mass and pion decay constant as obtained by the
ETM collaboration in large scale simulations with maximally twisted mass fermions and two
mass degenerate flavours of light quarks. We discuss the continuum, chiral and infinite volume
extrapolation of these quantities as well as the extraction of low energy constants, and investigate
possible systematic uncertainties.
