In another thread (on Oppenheimer-Snyder collapse), I posted a link to some lecture notes on gravitational collapse. Checking on the author, I find he is extremely prolific on many fundamental areas of GR (from the computational standpoint). Of particular interest:

catch phrase: you probably cannot produce super-extremal Kerr black hole

If two bodies collide, gamma factor does contribute to likelihood of forming a BH;

LHC hasn't got a chance to produce them, though.
