On-Mass-Shell Renormalization of the $⟨\bar{t}t⟩$ Contribution to the $\Delta I=1/2$ $s\leftrightarrow d$ Self-Energy Transition

M. R. Ahmady, V. Elias, N. C. A. Hill

In $⟨\bar{t}t⟩$-scenarios for dynamical electroweak symmetry breaking, the presence of a very large t-quark condensate necessarily generates an $s\leftrightarrow d$…
