We study exclusive quarkonium production in the dipole picture at next-to-leading order (NLO) accuracy, using non-relativistic expansion for wavefunction. The light cone wave functions needed have typically been available only tree level, either phenomenological models or nonrelativistic limit. Here, we discuss compatibility of approach and compute NLO relativistic corrections to light-cone fun...

We report lifetime measurements for three of the 5d96p levels in Au II and relativistic multiconfiguration Dirac–Fock (MCDF) calculations of lifetimes and transitions probabilities in this ion. The work was motivated by significant disagreements between previous experimental 5d96p lifetimes, obtained by means of the beam–foil (BF) method and theoretical data based on Hartree–Fock calculations i...

We revise the conventional nuclear effects of Fermi motion, binding and pionic effects in deep inelastic lepton scattering using a relativistic formalism for an interacting Fermi sea and the local density approximation to translate results from nuclear matter to finite nuclei. In addition we also consider effects from ρ-meson renormalization in the nucleus. The use of nucleon Green’s functions ...

The relativistic many-body perturbation theory with the optimized Dirac zeroth approximation is applied to calculation of some fundamental characteristics hyperfine structure middle and heavy Li-like multicharged ions. relativistic, exchange-correlation other corrections are accurately taken into account. orbital basis set generated in optimal performance gauge invariance principle. There liste...

In this paper, at first we have formulated the lowest order constrained variational method for the relativistic case of an interacting fermion system at finite temperature. Then we have used this formalism to calculate some thermodynamic properties of liquid in the relativistic regime. The results show that the difference between total energies of relativistic and non-relativistic cases of liqu...

Two aspects of the relativistic version of the EinsteinPodolsky-Rosen-Bohm (EPRB) experiment with massive particles are discussed: (a) a possibility of using the experiment as an implicit test of a relativistic center-of-mass concept, and (b) in uence of the relativistic e ects on degree of violation of the Bell inequality. The nonrelativistic singlet state average h j~a ~ ~b ~ j i = ~a ~b is r...
