Abstract

Technicolor represents a viable alternative to the Higgs mechanism for generating gauge boson masses. Searches for technicolor particles $\rho_T$ and $\pi_T$ 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 $(M_{\pi_T},M_{\rho_T})$ plane. The $\rho_T$ production is excluded for all $90 M_{\rho_T} 206.7$ GeV/c$^2$. Assuming a point-like interaction of the $\pi_T$ with gauge bosons, an absolute lower limit on the charged $\pi_T$ mass at 95\% CL is set at 79.8 GeV/c$^2$, independently of other parameters of the technicolor model
