Systematic errors of transition form factors extracted by means of light-cone sum rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
This talk presents results of our study of heavy-to-light transition form factors extracted with the help of light-cone sum rules. We employ a model with scalar particles interacti…
Systematic errors of bound-state parameters extracted by means of SVZ sum rules
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
This talk presents the results of our study of systematic errors of the ground-state parameters obtained by Shifman-Vainshtein-Zakharov (SVZ) sum rules. We use the harmonic-oscilla…
Twisted mass QCD in the charm sector
B. Blossier, G. Herdoiza, S. Simula
We present preliminary results for the charm quark mass and the and mesons decay constants and from a lattice QCD calculation with = 2 d…
Can one control systematic errors of QCD sum rule predictions for bound states?
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
We study the possibility to control systematic errors of the ground-state parameters obtained by Shifman-Vainshtein-Zakharov (SVZ) sum rules, making use of the harmonic-oscillator…
Renormalisation of quark bilinears with Nf=2 Wilson fermions and tree-level improved gauge action
P. Dimopoulos, R. Frezzotti, G. Herdoiza +4
We present results for the renormalisation constants of bilinear quark operators, using the Nf=2 twisted mass Wilson action at maximal twist (which guarantees automatic O(a) improv…
Light quark masses and pseudoscalar decay constants from Nf=2 twisted mass QCD
Vittorio Lubicz, Silvano Simula, Cecilia Tarantino
We present the results of the lattice QCD calculation of the average up-down and strange quark masses and of the light meson pseudoscalar decay constants, recently performed with N…
