Top quark condensate
Webscalar field(s). This is the basic idea of top quark condensation, as well as technicolor (TC) models. In such frameworks, the Higgs isodoublet is a condensate of fermion-antifermion … WebIn Quantum chromodynamics (QCD) the chiral condensate is also called the quark condensate. This property of the QCD vacuum is partly responsible for giving masses to hadrons (along with other condensates like the gluon condensate).
Top quark condensate
Did you know?
WebThe QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non-perturbative vacuum state, characterized by non-vanishing condensates such as the gluon condensate and the quark condensate in the complete theory which includes quarks. The presence of these condensates characterizes the confined phase of quark matter. WebMar 12, 1996 · In the light of recent discovery of a very heavy top quark, we reexamine the top quark condensate model proposed by Miransky, Tanabashi and Yamawaki (MTY) and by Nambu. We first review the original MTY formulation based on the ladder Schwinger-Dyson equation and the Pagels-Stokar formula. It is particularly emphasized that the critical …

WebOct 7, 2013 · We discuss the quark masses in a top condensate model where not only two quark but also four quark composite states may exist. Webζ, with q= u,d, is the current-quark mass at a renormalization scale ζ; and h¯qq i0 ζ is the chiral-limit vacuum quark condensate, with a precise definition of the chiral limit given below in Eqs.(8), (9). In arriving at Eq.(1) using standard methods, one makes truncations; namely, soft-pion techniques [20] have been used to re-
WebMay 10, 1990 · The gap equation in dressed ladder approximation is solved numerically and the solutions ∑ t ( p) are used to determine 〈 t t〉 and the decay constants F±, F0, as well as the top quark mass itself. We also discuss the cut-off dependence of these results, and comment on the fine-tuning problem.
