8 Dec 1999 | | Journal: | Phys.Lett. B483 (2000) 203-209 | | Subject: | hep-ph hep-ex | | Abstract: | In extra dimension theories if the gauge bosons of the standard model propagate in the bulk of the extra dimensions then they will have Kaluza-Klein excitations that can couple to the standard model fermions. In this paper we study the effects of the first excited Kaluza-Klein mode of the W on single top production at the Tevatron. We find that the cross section for the single top production can be significantly reduced if the mass of the first Kaluza-Klein excited $W sim 1$ TeV. Hence, a measurement of the single top production cross section smaller than the standard model prediction would not necessarily imply $V_{tb} <1$ or evidence of extra generation(s) of fermions mixed with the third generation. | | Source: | arXiv, hep-ph/0001059 | | Services: | Forum | Review | PDF | Favorites | |
