QCD Green Functions and their Application to Hadron Physics
In a functional approach to QCD the infrared behaviour of Landau gauge Green functions is investigated. It can be proven that the ghost Dyson-Schwinger equation implies the Gribov-Zwanziger horizon condition. Its relation to the Kugo-Ojima confinement scenario is elucidated. Positivity violation for gluons is demonstrated, and the analytic structure of the gluon propagator is studied. Quark con...
متن کاملQCD and Hadron Physics at CDF
Results to be reported below are mostly based on the Run II data. To remind, CDF has undergone a number of major upgrades for the Run II, with a good fraction of the old CDF scrapped and replaced with brand new apparatus, designed to work at higher luminosity, providing better performance, and adding new capabilities. The CDF-II tracker can do the full track reconstruction, including 3D-vertex,...
متن کاملLow Energy Hadron Physics in Holographic QCD
We present a holographic dual of four-dimensional, large Nc QCD with massless flavors. This model is constructed by placing Nf probe D8-branes into a D4 background, where supersymmetry is completely broken. The chiral symmetry breaking in QCD is manifested as a smooth interpolation of D8-D8 pairs in the supergravity background. The meson spectrum is examined by analyzing a five-dimensional Yang...
متن کاملLattice QCD meets experiment in hadron physics
We review recent results in lattice QCD from numerical simulations that allow for a much more realistic QCD vacuum than has been possible before. Comparison with experiment for a variety of hadronic quantities gives agreement to within statistical and systematic errors of 3%. We discuss the implications of this for future calculations in lattice QCD, particularly those which will provide input ...
متن کاملHadron Structure Functions from Lattice QCD – 1997
We review the status of lattice calculations of the deep-inelastic structure functions of the nucleon. In addition, we present some results on the pion and rho structure functions.
