A Tumbling Top-Quark Condensate Model
We propose a renormalizable model with no fundamental scalars which breaks itself in the manner of a “tumbling” gauge theory down to the standard model with a top-quark condensate. Because of anomaly cancellation requirements, this model contains two color sextet fermions (quixes), which are vector-like with respect to the standard model gauge group. The model also has a large number of pseudo-...
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 کاملHamiltonian field theoretical model for a light quark condensate
I propose an alternative Hamiltonian field theoretical model for a light quark condensate that is compatible with QCD in the deep infrared. Key electroweak data on flavourless pseudoscalar mesons are used for necessary renormalizations. Light quark inertial masses are redefined in a new and broader theoretical context. PACS. : 11.30.Rd, 12.15.Ff, 14.65.Bt key words: fermion condensates, light q...
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 کاملPossible Color Octet Quark-Anti-Quark Condensate in the Instanton Model
Inspired by a recent proposal for a Higgs description of QCD we study the possible formation of a color-octet/flavor-octet quark-anti-quark condensate in the instanton liquid model. For this purpose we calculate two-point correlation functions of color-singlet and octet quark-anti-quark operators. We find long range order in the standard 〈ψ̄ψ〉 channel, but not in the color-octet channel. We emph...
