The top quark mass and flavor mixing in a Seesaw model of Quark Masses
The top quark mass and the flavor mixing are studied in the context of a Seesaw model of Quark Masses based on the gauge group SU(2)L×SU(2)R×U(1). Six isosinglet quarks are introduced to give rise to the mass hierarchy of ordinary quarks. In this scheme, we reexamine a mechanism for the generation of the top quark mass. It is shown that, in order to prevent the Seesaw mechanism to act for the t...
متن کاملTop quark production near threshold and the top quark mass
We consider top-anti-top production near threshold in e+e− collisions, resumming Coulomb-enhanced corrections at next-to-next-to-leading order (NNLO). We also sum potentially large logarithms of the small top quark velocity at the next-toleading logarithmic level using the renormalization group. The NNLO correction to the cross section is large, and it leads to a significant modification of the...
متن کاملTop Quark Mass and Supersymmetry
We summarize the expectations for the top quark mass in supersymmetric models and discuss the potential implications of its value measured by the CDF group in Fermilab.
متن کاملPhenomenology of a top quark seesaw model
The top quark seesaw mechanism offers a method for constructing a composite Higgs field without the usual difficulties that accompany traditional technicolor or topcolor theories. The focus of this article is to study the phenomenology of the new physics required by this mechanism. After establishing a set of criteria for a plausible top quark seesaw theory, we develop two models, the first of ...
متن کاملTop quark mass measurements at D0
We present the most recent measurements of the mass of the top quark at D0 using proton-antiproton collisions at √ s = 1.96 TeV at the Fermilab Tevatron collider. The world average for the mass of the top quark is 170.9 ± 1.8 GeV/c.
