Study on PGBs Correction to qq→tt at the Tevatron in the Technicolor Models

  • We calculate the Pseucdo-Godstone-Bosons(PGBs) corrections of order αm2t to qq→tt at the Tevatron in the framewords of the one generation technicolor model(OGTC) and a minimal technicolor model(MTC) with a massless weak doublet recently presented by C.D. Carone and H.Georgi.The PGBs correction can decrease the total tt production cross section by as much as-38% for top mass of 176GeV and color octet PGBs mass of 150GeV in the OGTC model,which is potentially observable at the Tevatron.However,the results show that the corrections to the pprocess are unmeasurablly small in the MTC model.
