Search for Technicolor with DELPHI
The DELPHI Collaboration, J. Abdallah
Abstract
Technicolor represents a viable alternative to the Higgs mechanism for generating gauge boson masses. Searches for technicolor particles rhoT and piT have been performed in the data collected by the DELPHI experiment at LEP at centre-of-mass energies between 192 and 208 GeV corresponding to an integrated luminosity of 452 pb-1. Good agreement is observed with the SM expectation in all channels studied. This is translated into an excluded region in the (MpiT,MrhoT) plane. The rhoT production is excluded for all 90 < MrhoT < 206.7 GeV/c2. Assuming a point-like interaction of the piT with gauge bosons, an absolute lower limit on the charged piT mass at 95% CL is set at 79.8 GeV/c2, independently of other parameters of the technicolor model.
