A strategy for the computation of m_b including 1/m terms
Michele Della Morte, Nicolas Garron, Rainer Sommer +1
We consider HQET including the first order correction in 1/m. A strategy for the computation of the b-quark mass is discussed. Only two quantities Phi_1/2 have to be considered in…
Towards a non-perturbative computation of the RGI strange quark mass with two dynamical flavors
Michele Della Morte, Roland Hoffmann, Francesco Knechtli +4
The non-perturbative running of the quark mass in the Schroedinger functional scheme is computed over a large energy range (covering scales differing by two orders of magnitude). T…
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…
Fundamental parameters of QCD
Rainer Sommer, Hartmut Wittig
The theory of strong interactions, QCD, is described in terms of a few parameters, namely the strong coupling constant alpha_s and the quark masses. We show how these parameters ca…
The -parameter and of quenched QCD
Rainer Sommer
We explain how scale dependent renormalized quantities can be computed using lattice QCD. Two examples are used: the running coupling and quark masses. A reliable computation of th…
