Dimensional Reduction is applied to QCD in order to compute various renor-malization constants in the DR scheme at higher orders in perturbation theory. In particular, the β function and the anomalous dimension of the quark masses are derived to three-loop order. Special emphasis is put on the proper treatment of the so-called ε-scalars and the additional couplings which have to be considered.
متن کاملDimensional Reduction applied to QCD at higher orders
Dimensional Regularization (DREG) [2] has proven extremely successful for the evaluation of higher order corrections in quantum field theory, mostly because it preserves gauge invariance and thus does not interfere with the renormalizability of the Standard Model or QCD. Many techniques for evaluating Feynman diagrams have been developed within the framework of DREG, so perturbation theory heav...
متن کاملMatching QCD and HQET at three loops
QCD problems with a single heavy quarkQ can be treated in a simpler effective theory — HQET, if there exists a 4-velocity v such that the heavyquark momentum is p = mv+k (m is the on-shell mass) and the characteristic residual momentum is small: k ≪ m. QCD operators can be written as series in 1/m via HQET operators; the coefficients in these series are determined by matching on-shell matrix el...
متن کاملThe QCD Splitting Functions at Three Loops: Methods and Results
We have computed the complete next-to-next-to-leading order (NNLO) contributions to the splitting functions governing the evolution of unpolarized parton densities in perturbative QCD. Our results agree with all partial results available in the literature. We illustrate the methods used for this calculation with some examples and display selected results to show the size of the NNLO corrections...
متن کاملTwo-loop parameter relations between dimensional regularization and dimensional reduction applied to SUSY-QCD
The two-loop relations between the running gluino-quark-squark coupling, the gluino and the quark mass defined in dimensional regularization (DREG) and dimensional reduction (DRED) in the framework of SUSY-QCD are presented. Furthermore, we verify with the help of these relations that the three-loop β-functions derived in the minimal subtraction scheme combined with DREG or DRED transform into ...
