D0, CDF: no Higgs or supersymmetry yet

There have been lots of rumors. But yesterday, both D0 and CDF collaborations have submitted a proceedings paper about the status of the searches:

Searches for Higgs and SUSY at the Tevatron
and there is nothing. The CP-odd SUSY Higgs around 160 GeV suggested by CDF was annihilated by D0 and nothing else is seen.

I think we will have to wait for the LHC and the comments that the life of the Tevatron should be extended are not based on scientific arguments. Nevertheless, if you want to feel a 50% likelihood that a CP-odd supersymmetric Higgs boson between 150 and 160 GeV has been found by the Fermilab at 3+ sigma, see Tommaso Dorigo. Incidentally, the Italian journalists have determined that Prof Lisa Randall is a "body of the beast Che Guevara". ;-)

Gordon Kane et al. have submitted a paper about methods to find signatures to distinguish among classes of stringy vacua at the LHC. I wonder whether one of the notorious crackpots who say that string theory can't be tested has ever seen a real paper about particle physics.
