Remarkable coincidence for the top Yukawa coupling and an approximately massless bound state
Remarkable coincidence for the top Yukawa coupling and an approximately massless bound state
We calculate, with several corrections, the nonrelativistic binding by Higgs exchange and gluon exchange between six top and six antitop quarks (actually replaced by left-handed $b$ quarks from time to time). The remarkable result is that, within our calculational accuracy of the order of 14% in the top-quark Yukawa coupling …
