It contains total energy roughly 30 TeV localized in a region of radius 0.05 fm. A detailed description of these numerical results is presented.12 pages, 8 figures, uses RevTeX4; v2: expanded results section, fixed typosHigh Energy Physics - TheoryHigh Energy Physics - LatticeHigh Energy Physics - PhenomenologyAdaptation and Self-Organizing Systemstext
