Tommaso Dorigo of the CDF collaboration at the Tevatron has just posted (with commentary), the slides for his talk at Moriond later this month about the status of the search for the Higgs at the Tevatron. The bottom line is that with the data they have already analyzed they are still quite a ways from being able to see the Higgs, but, if its mass is just above the lower limit set by LEP2, they should be able to see it by two years from now. With quite optimistic assumptions about the performance of the Tevatron, by the end of 2009 they should be able to see the Higgs if its mass is less than 180 Gev. He ends by saying that at “95% confidence level” he thinks the Tevatron will be able to end up seeing a Higgs up to 135 Gev mass, and if its mass is just above the LEP2 limit at 115 Gev, they should have 3 sigma evidence for its existence.
By 2009, the LHC should be producing data and putting the Tevatron out of the Higgs discovery business. For a bewilderingly complicated schedule of the LHC construction and installation, go here. From what I can tell, they are still on track for first colliding beams in spring of 2007.
Update: See Tommaso’s comment to this posting for a clarification. By “seeing the Higgs” I didn’t mean to imply that they would be able to prove the Higgs was there, just that they would be starting to see some evidence of its existence.
