Fractal Propagators in QED and QCD and Implications for the Problem of Confinement
We show that QED radiative corrections change the propagator of a charged Dirac particle so that it acquires afractional anomalous exponent connected with the fine structure constant. The result is a nonlocal object whichrepresents a particle with a roughened trajectory whose fractal dimension can b...
