Critical behaviour in the Einstein-Yang-Mills system — •Oliver Rinne and Maciej Maliborski — Albert-Einstein-Institut, Potsdam

The Einstein-Yang-Mills system displays a variety of critical phenomena in gravitational collapse. Two new results are reported here. By tuning two parameters in the initial data, the magnetic Reissner-Nordström solution appears as an approximate intermediate attractor separating the critical line of coloured black hole solutions of opposite sign. The second result concerns the influence on critical collapse of a sphaleron contribution in the ansatz for the spherically symmetric Yang-Mills field.
