Four and Three Loop Calculations in QCD : Theory and Applications ∗
نویسنده
چکیده
The talk briefly reviews the current state of the art in doing multiloop QCD calculations in a completely analytic way. In particular, we discuss recent analytical calculations of 4-loop O(α 3 s) gluino contribution to R(s) and its implications to Γ tot (Z → hadrons) and Γ(τ − → ν τ + hadrons);

QCD pressure up to four loops at finite temperature and density
In recent years the perturbative expansion of the pressure of massless QCD has been driven to order glng at high temperatures and finite chemical potentials, which has required calculations up to three-loop order in the full theory and up to four-loop order in three-dimensional effective theories. In the present paper we briefly review the theoretical background behind this work and explain som...
متن کاملAsymptotic Freedom and QCD–a Historical Perspective
It was a pleasure to attend Loops and Legs in Quantum Field Theory, 2004, and to deliver a historical account of the origins of QCD. The talks delivered at this exciting meeting are a dramatic illustration of how far QCD has developed since its inception thirty years ago. Current and forthcoming experiments are performing tests of QCD with amazing precision, and theoretical calculations of pert...
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 کاملPerturbative Thermodynamics of Lattice QCD with Chiral-Invariant Four-Fermion Interactions
Lattice QCD with additional chiral-invariant four-fermion interactions is studied at nonzero temperature. Staggered Kogut-Susskind quarks are used. The four-fermion interactions are implemented by introducing bosonic auxiliary fields. A mean field treatment of the auxiliary fields is used to calculate the model’s asymptotic scale parameter and perturbative thermodynamics, including the one-loop...
متن کاملFour-loop moments of the heavy quark vacuum polarization function in perturbative QCD
New results at four-loop order in perturbative QCD for the first two Taylor coefficients of the heavy quark vacuum polarization function are presented. They can be used to perform a precise determination of the charmand bottom-quark mass. Implications for the value of the quark masses are briefly discussed.
