| 摘 要： | 本文分别在多标度ＴＣ模型（ＭＴＭ）与带有一个标量子的ＴＣ模型（ＭＴＣ）中研究了赝标哥尔斯通粒子（ＰＧＢ）对Ｔｅｖａｔｒｏｎ上ｔｏｐ夸克对产生截面的单圈贡献．我们发现在ＭＴＭ中该贡献是显著的，当ｔｏｐ夸克的质量取１７６ＧｅＶ，色八重态ＰＧＢ的质量可以取到６００ＧｅＶ时，该修正值达到２９％，这是很有实验意义的，然而在ＭＴＣ中，该修正较小，不可观测

| Abstract: | We calculate the Pseudo Goldstone Bosons(PGBs)corrections to q→t of order am 2 t at the Tevatron in the frameworks of the multiscale technicolor model (MTM)and a minimal technicolor model (MTC)with a massless weak doublet recently presented by C.D.Carone and H.Georgi.The PGBs correction can enhance the total t production cross section by as much as 29% for top mass of 176 Gev and colot octer PGBs mass of 600 Gev in the MTM model, which is potentially observable at the Tevatron.However,the results show taht the process is unmeasurable small in MTC model. |
