The Running Coulomb Potential and Lamb Shift in QCD
The QCD β-function and the anomalous dimensions for the Coulomb potential and the static potential first differ at three loop order. We evaluate the three loop ultrasoft anomalous dimension for the Coulomb potential and give the complete three loop running. Using this result, we calculate the leading logarithmic Lamb shift for a heavy quark-antiquark bound state, which includes all contribution...
متن کاملLamb Shift in Muonic Hydrogen
The Lamb shift in muonic hydrogen continues to be a subject of experimental and theoretical investigation. Here my older work on the subject is updated to provide a complementary calculation of the energies of the 2p-2s transitions in muonic hydrogen. Introduction The energy levels of muonic atoms are very sensitive to effects of quantum electrodynamics (QED), nuclear structure, and recoil, sin...
متن کاملQuantum electrodynamics in strong electric fields: the ground-state Lamb shift in hydrogenlike uranium.
X-ray spectra following radiative recombination of free electrons with bare uranium ions (U92+) were measured at the electron cooler of the ESR storage ring. The most intense lines observed in the spectra can be attributed to the characteristic Lyman ground-state transitions and to the recombination of free electrons into the K shell of the ions. Our experiment was carried out by utilizing the ...
متن کاملCoulomb Scattering in a Strong Magnetic Field
The presence of a strong magnetic eld intrinsically changes the orbit of electrons in their Coulomb interactions with ions for a range of parameters. The characteristic scale for the orbit modi cation is r0 = (Zme=4 0B) where Ze is the ion charge, me the electron mass and B the magnetic eld strength. The scale length is comparable to the interparticle spacing when n 1=3 e r0 = (!pe=!ce) 2=3(Z=4...
متن کاملTechniques in Analytic Lamb Shift Calculations
Quantum electrodynamics has been the first theory to emerge from the ideas of regularization and renormalization, and the coupling of the fermions to the virtual excitations of the electromagnetic field. Today, bound-state quantum electrodynamics provides us with accurate theoretical predictions for the transition energies relevant to simple atomic systems, and steady theoretical progress relie...
