Web24 jan. 2011 · The electric dipole form factor (EDFF) of the nucleon stemming from the QCD (theta) over bar term and from the quark color-electric dipole moments is calculated in chiral perturbation theory to sub-leading order. This is the lowest order in which the isoscalar EDFF receives a calculable, non-analytic contribution from the pion cloud. Webbinding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system. Binding energy is especially applicable to subatomic particles in atomic nuclei, to electrons bound to nuclei in atoms, and to atoms and ions bound together in crystals. Nuclear binding energy is the energy required to …
WebWe present preliminary results from an investigation into the magnetic properties of the nucleon using the background field method of lattice QCD. The method involves introducing a uniform magnetic field across the lattice and measuring the resulting energy shift.
