The three-loop cusp anomalous dimension in QCD
We present the full analytic result for the three-loop angle-dependent cusp anomalous dimension in QCD. With this result, infrared divergences of planar scattering processes with massive particles can be predicted to that order. Moreover, we define a closely related quantity in terms of an effective coupling defined by the light-like cusp anomalous dimension. We find evidence that this quantity...
متن کاملQCD thermodynamics with colour-sextet quarks
We study QCD with two flavours of colour-sextet quarks as a candidate walking-Technicolor theory. We simulate lattice QCD with two flavours of colour-sextet staggered quarks at finite temperatures to observe the scales of confinement and chiral-symmetry breaking. These should give us some indication as to whether the massless theory has an infrared fixed point making it a conformal field theory...
متن کاملBose-Einstein or HBT correlations and the anomalous dimension of QCD
The Bose-Einstein (or HBT) correlation functions are evaluated for the fractal structure of QCD jets. These correlation functions have a stretched exponential (or Lévy-stable) form. The anomalous dimension of QCD determines the Lévy index of stability, thus the running coupling constant of QCD becomes measurable with the help of two-particle Bose-Einstein correlation functions. These considerat...
متن کاملAnomalous Dimension and Local Charges
AdS space is the universal covering of a hyperboloid. We consider the action of the deck transformations on a classical string worldsheet in AdS5 × S. We argue that these transformations are generated by an infinite linear combination of the local conserved charges. We conjecture that a similar relation holds for the corresponding operators on the field theory side. This would be a generalizati...
متن کاملCusp anomalous dimension in maximally supersymmetric
This talk is mainly based on the work [1] performed in collaboration with B. Basso1 and G. Korchemsky1, where the method of strong coupling expansion of the cusp anomalous dimension was found. The cusp anomalous dimension [2], called also the cusp, is a physical observable, which appears in many branches of particle physics. It is related with the logarithmic growth of the anomalous dimensions ...
