No Higgs bosons ? But new fifth force may have been discovered

The announcement that the CDF experiment at Fermilab's Tevatron collider has seen evidence for the production of a new particle has created a great deal of interest. There's some cynicism about the result, coming as it does at a time when the Tevatron is about to be shut down and the future of US high energy physics is rather uncertain - but despite the politics, this really would be a revolutionary result if it's confirmed.

Kenneth Lane (Boston U), Eichten and Fermilab physicist Adam Martin suggest that a technipion with a mass of about 160 GeV could be the mysterious particle producing the two jets. "If this is real, I think people will give up on the idea of looking for the Higgs and begin exploring this rich world of new particles," Lane says.

IMO: Early technicolor physics was based on Chromodynamics. But this newish Technicolor physics proposes a new 5th force, something like the strong force and it is able to give particles their mass. Obviously, this could also greatly affect cosmology also.
