The effect of sea quark electromagnetic charge on meson masses is investigated, and first results for full QED + QCD low-energy constants are presented. The electromagnetic charge for sea quarks is incorporated in quenched QED + full QCD lattice simulations by a reweighting method. The reweighting...
An analysis is presented of radiative corrections due to fermion vacuum polarization for the process eμ→eμ and the full O(α2) final state QED radiative correction to . It is demonstrated that in both cases, the corrections contain next-to-leading logarithmic terms of the form α2 ln ...
In a previous paper we have shown how the Wilsonian renormalization group naturally leads to the equivalence of the standard QED with a matter-only theory. In this paper we give an improved explanation of the equivalence and discuss, as an example, the equivalence of a chiral QED in the Hig...
This equation defines the so-called form factor σ(k,A), which encapsulates all non-trivial information about the pole structure of the full ghost propagator, in fact, if it vanishes we recover the free propagator expression. In order to implement the no-pole condition one has to integrate ...

A full-scale quantum algorithm always requires joint control over multiple quantum systems, which currently represent challenging problems in experimental quantum physics. If the quantum circuit model3 is considered, any joint system evolutions may be synthesized with small-system evolutions, i.e., ...

Quantum Physics\\The Bethe-Salpeter equation in a strong magnetic field is studied for positronium atom in an ultra-relativistic regime, and a (hypercritical) value for the magnetic field is determined, which provides the full compensation of the positronium rest mass by the binding energy in ...
