Two-loop parameter relations between dimensional regularization and dimensional reduction applied to SUSY-QCD
نویسنده
چکیده
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 each other. This result confirms the equivalence of the two schemes at the three-loop order, if applied to SUSY-QCD. PACS numbers: 11.25.Db 11.30.Pb 12.38.Bx

Dimensional 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 کاملOne-loop Singular Behaviour of QCD and SUSY QCD Amplitudes with Massive Partons
We discuss the structure of infrared and ultraviolet singularities in on-shell QCD and supersymmetric QCD amplitudes at one-loop order. Previous results, valid for massless partons, are extended to the case of massive partons. Using dimensional regularization, we present a general factorization formula that controls both the singular ǫ-poles and the logarithmic contributions that become singula...
متن کاملSupersymmetric Regularization, Two-Loop QCD Amplitudes and Coupling Shifts
We present a definition of the four-dimensional helicity (FDH) regularization scheme valid for two or more loops. This scheme was previously defined and utilized at one loop. It amounts to a variation on the standard ’t Hooft-Veltman scheme and is designed to be compatible with the use of helicity states for “observed” particles. It is similar to dimensional reduction in that it maintains an eq...
متن کاملRelation between the pole and the minimally subtracted mass in dimensional regularization and dimensional reduction to three-loop order
We compute the relation between the pole quark mass and the minimally subtracted quark mass in the framework of QCD applying dimensional reduction as a regularization scheme. Special emphasis is put on the evanescent couplings and the renormalization of the ε-scalar mass. As a by-product we obtain the three-loop on-shell renormalization constants ZOS m and Z OS 2 in dimensional regularization a...
متن کاملOne - loop helicity amplitudes for all 2 → 2 processes in QCD and N = 1 supersymmetric Yang - Mills theory
One-loop corrections to the helicity amplitudes of all 2 → 2 subprocesses are calculated in QCD and in N=1 supersymmetric Yang-Mills theory using two versions of dimensional regularization: the ‘t Hooft-Veltman scheme and dimensional reduction. Studying the structure of the soft and collinear singularities, we found universal transition rules for the squared matrix element which can be used to ...
