The hadronic vacuum polarization contributions to (g -2)μ below one GeV are dominated by the two-pion contribution. The latter can be described by the electromagnetic pion form factor. Unitarity and analyticity strongly constrain the latter. Unitarity, e.g., implies that the phase of the form factor
Properties of hedgehog solitons in a chiral quark model with nonlocal regulators are described. We discuss the formation of the hedgehog soliton, the quantization of the baryon number, the energetic stability, the gauging and construction of Noether currents with help of path-ordered P -exponents, a
