Quantum chromodynamics at high energy and statistical physics
When hadrons scatter at high energies, strong color fields, whose dynamics is described by quantum chromodynamics (QCD), are generated at the interaction point. If one represents these fields in terms of partons (quarks and gluons), the average number densities of the latter saturate at ultrahigh energies. At that point, nonlinear effects become predominant in the dynamical equations. The hadro...
متن کاملFrom Qcd at High Energy to Statistical Physics and Back
(1) The three linear terms in this equation correspond to the well-known BFKL equation. This has solutions growing like exp(ωPY ) (with ωP = 4 log(2)ᾱ) and thus violating the unitarity bound Txy ≤ 1. The last term, taking into account the scattering on both dipoles, is important when the scattering becomes of order 1 and restores unitarity. To deal with (1), one usually adopts in the mean-field...

متن کاملQuantum Chromodynamics at Colliders
QCD is the accepted (that is, the effective) theory of the strong interaction; studies at colliders are no longer designed to establish this. Such studies can now be divided into two categories. The first involves the identification of observables which can be both measured and predicted at the level of a few percent. Such studies parallel those of the electroweak sector over the past fifteen y...
متن کاملHeavy-quark Physics in Quantum Chromodynamics’
Heavy quarks can expose new symmetries and novel phenomena in QCD not apparent in ordinary hadronic systems. In these lectures I discuss the use of effective-Lagrangian and light-cone Fock methods to analyze exclusive heavy hadron decays such as Y + pp and B + XT, and also to derive effective SchrGdinger and Dirac equations for heavy quark systems. Two contributions to the heavy quark structure...
