چکیده
The decay width of the Z gauge boson into three jets has already been computed at the leading order (LO) including complete quark mass effects [1–3] where it has been shown that mass effects could be as large as 1% to 6%, depending on the value of the mass and the jet resolution parameter yc. In fact, these effects had already been seen in the experimental tests of the flavor independence of the strong coupling constant [4–8]. In view of that we proposed [3], together with the DELPHI collaboration [9], the possibility of using the ratio [3,6,7]

Next-to-leading order calculations of heavy quark three-jet production in e + e − annihilation are reviewed. Their application for the measurement of the b-quark mass at LEP/SLC and to the test of the flavour independence of the strong coupling constant are discussed. Prospects for future improvements are studied.

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 the Λ-parameter in the quenched approximation is presented.
