Trinucleon Electromagnetic Form Factors and the Light-Front Hamiltonian Dynamics
This contribution briefly illustrates preliminary calculations of the electromagnetic form factors of 3He and 3H, obtained within the Light-front Relativistic Hamiltonian Dynamics, adopting i) a Poincaré covariant current operator, without dynamical two-body currents, and ii) realistic nuclear bound states with S, P and D waves. The kinematical region of few (GeV/c)2, relevant for forthcoming T...
متن کاملLight - Front Hadron Dynamics and AdS / CFT Correspondence ∗
A remarkable consequence of the AdS/CFT correspondence is the nonperturbative derivation of dimensional counting rules for hard scattering processes. Using string/gauge duality we derive the QCD power behavior of light-front Fock-state hadronic wavefunctions for hard scattering in the large-r region of the AdS space from the conformal isometries which determine the scaling of string states as w...
متن کاملLight - Front Dynamics and Light - Front Qcd
In this article, I will try to address some aspects of nonperturbative QCD. The theory of nonperturbative QCD (at the hadronic scale) has indeed not been well defined at the present time. Firstly, how much we can understand about the real theory of the strong interaction from the canonical QCD structure is totally unknown. Secondly, there are in the literature many models or effective theories ...
متن کاملCovariance , Dynamics and Symmetries , and Hadron Form Factors
We summarise applications of Dyson-Schwinger equations to the theory and phenomenology of hadrons. Some exact results for pseudoscalar mesons are highlighted with details relating to the U A (1) problem. We describe inferences from the gap equation relating to the radius of convergence for expansions of observables in the current-quark mass. We recapitulate upon studies of nucleon electromagnet...
متن کاملSpacelike and Timelike Normal Curves in Minkowski Space-time
We define normal curves in Minkowski space-time E4 1 . In particular, we characterize the spacelike normal curves in E4 1 whose Frenet frame contains only non-null vector fields, as well as the timelike normal curves in E4 1 , in terms of their curvature functions. Moreover, we obtain an explicit equation of such normal curves with constant curvatures.
