Top quark condensate
WebMay 1, 1992 · We study the sensitivity of the top-quark and Higgs-boson masses in the top-quark condensate model to two-loop radiative corrections. The composite theory, including a higher-dimensional Suzuki operator, provides the two-loop renormalization-group equations of the standard model with ultraviolet boundary conditions. WebApr 30, 2024 · In Quantum Chromodynamics ( QCD) a Chiral perturbation theory ( ChPT) is not available to create a 'top Quark condensate' where one could extend the top Quark's lifetime.

The top quark, sometimes also referred to as the truth quark, (symbol: t) is the most massive of all observed elementary particles. It derives its mass from its coupling to the Higgs Boson. This coupling is very close to unity; in the Standard Model of particle physics, it is the largest (strongest) coupling at the scale of the weak interactions and above.
