نویسندگان
چکیده
The present status of quantum electrodynamics (QED) theory of heavy few-electron ions is reviewed. The theoretical results are compared with available experimental data. A special attention is focused on tests of QED at strong fields and on determination of the fundamental constants. A recent progress on calculations of the QED corrections to the parity nonconserving 6s-7s transition amplitude in neutral Cs is also discussed.

Accurate calculations of the binding energies, the hyperfine splitting , the bound-electron g-factor, and the parity nonconservation effects in heavy few-electron ions are considered. The calculations include the relativistic, quantum electrodynamic (QED), electron-correlation, and nuclear effects. The theoretical results are compared with available experimental data. A special attention is foc...

In the framework of perturbative QCD, double inclusive cross sections for high pt parton production in nucleus-nucleus collisions are computed with multiple rescattering taken into account. The induced long-range correlations between numbers of jets at forward and backward rapidities are found to reach 10÷ 20% for light nuclei at √ s = 200 GeV/c and to be suppressed for heavy nuclei and LHC ene...

A light front field theory for finite temperature and density is currently being developed. It will be used here to describe the transition region from quark matter to nuclear matter relevant in heavy ion collisions and in the early universe. The energy regime addressed is extremely challenging, both theoretically and experimentally. This is because of the confinement of quarks, the appearance ...

Elliptic flow measurements are presented and discussed with emphasis on the hydrodynamic character of the hot and dense QCD matter created in heavy ion collisions at RHIC. Predictions from perfect fluid hydrodynamics for the scaling of the elliptic flow coefficient v2 with eccentricity, system size and transverse energy are validated. A universal scaling for the flow of both mesons and baryons ...

We derive the two-particle fluctuation correlator in a thermal gas of π-mesons to the lowest order in an interaction due to a resonance exchange. A dia-grammatic technique is used. We discuss how this result can be applied to event-by-event fluctuations in heavy-ion collisions, in particular, to search for the critical point of QCD. As a practical example, we determine the shape of the rapidity...
