TY - JOUR ID - citeulike:3512196 L3 - citeulike-article-id:3512196 N2 - We calculate, with several corrections, the non-relativistic binding by Higgs exchange and gluon exchange between six top and six anti-top 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 g_t, the experimental running top quark Yukawa coupling g_t = >.935 happens to have just that value which gives a perfect cancellation of the unbound mass = 12 top quark masses by this binding energy. In other words the bound state is massless to the accuracy of our calculation!
