Unifying Aspects of Light- and Heavy-Systems,tive, symmetry preserving truncation that enables the proof of exact results. Key to the DSE’s efficacious application is their expression of the materially important momentum-dependent dressing of parton propagators at infrared length-scales, which is responsible for the magnitude of constituent-qu

One-Loop Corrections to Polarization Observables,ables in specific. Many high order radiative corrections exists for rates but not many . radiative corrections exist for polarization observables. The radiative correction calculations for polarization observables are somewhat more complicated than those for rates. They tend to be smaller than those

Exclusive Rare Decays of , and , Mesons in a Relativistic Quark Model, derive a four-fold angular decay distribution for this process in terms of helicity amplitudes including lepton mass effects. The four-fold angular decay distribution allows to define a number of physical observables which are amenable to measurement. Second, we calculate the relevant form factors

Spectroscopy of Baryons Containing Two Heavy Quarks,on relativistic three quark Hamiltonian with the perturbative Coulomb-like and non perturbative string interactions and the specific mass term. After outlining the approach methods of calculations of the baryon eigen energies and some simple applications are explained in details. A mass of 3620 MeV

Extraction of the Strong Coupling Constant and Strange Quark Mass from Semileptonic , Decays,QCD parameters is discussed. I show in some details how one can extract an accurate numerical value for the strong coupling constant from the .-lepton decay rate into hadrons. As a related topic I discuss some peculiarities of the precise definition of the quark mass in theories with confinement and

Heavy Flavor Production off Protons and in a Nuclear Environment,A unified description based on the light-cone color-dipole approach is employed in all cases. A good agreement with available data is achieved without fitting to the data to be explained, and nontrivial predictions for future experiments are made. The key phenomena under discussion are: (i) formatio

Heavy Mesons and Impact Ionization of Heavy Quarkonia, in the deconfined phase. We investigate the consequences of this qualitative change in the hadron spectrum on final state interactions of charmonium in hot and dense matter, and show that the Mott effect for D-mesons leads to a critical enhancement of the J/. dissociation rate. Anomalous J/. suppre
