Heavy quark propagators with improved precision using domain decomposition
A. Juttner, M. Della Morte
We show that, in four dimensions, the quark propagator is affected by round-off errors for large values of the quark mass am and the time extent T/a even when double precision arit…
Precision Lattice Computations in the Heavy Quark Sector
Andreas Juttner
The phenomenology of the pseudo scalar mesons D_s and B_s and of the vector mesons D_s* and B_s* was investigated in simulations of quenched lattice QCD. The work is particularly f…
Non-perturbative tests of HQET in small-volume quenched QCD
Jochen Heitger, Andreas Juttner, Rainer Sommer +1
We quantitatively investigate the quark mass dependence of current matrix elements and energies, calculated over a wide range of quark masses in the continuum limit of small-volume…
Precision computation of the leptonic D_s-meson decay constant in quenched QCD
Andreas Juttner, Juri Rolf
We summarize a computation of the leptonic decay constant f_D_s of the D_s-meson in quenched QCD on the lattice. We perform a direct simulation at the masses of the strange and the…
