چکیده

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 gt, the experimental running top quark Yukawa coupling gt = .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!

Nw Nc 6= 0,∞ held fixed. Since for Nw ≥ 3 only one renormalizable Yukawa coupling per family exists and there is no mixing between families the limit is appropriate for the description of the effects of a heavy top quark when all the other fermions are taken to be massless. The large N = √ NcNw expansion is expected to be no worse quantitatively in this model that in the purely scalar case and ...

New Bound States of Top-anti-Top Quarks and T-balls Production at Colliders (Tevatron, LHC, etc.)

The present talk is based on the assumption that New Bound States (NBSs) of top-anti-top quarks (named T-balls) exist in the Standard Model (SM): a) there exists the scalar 1S–bound state of 6t+6t̄ — the bound state of 6 top-quarks with their 6 anti-top-quarks; b) the forces which bind these top-quarks are very strong and almost completely compensate the mass of the 12 top-anti-top-quarks formin...

A Hard Convex Core Yukawa Equation of State for Nonassociated Chain Molecules

The compressibility factor of nonassociated chain molecules composed of hard convex core Yukawa segments was derived with SAFT-VR and an extension of the Barker-Henderson perturbation theory for convex bodies. The temperature-dependent chain and dispersion compressibility factors were derived using the Yukawa potential. The effects of temperature, packing fraction, and segment number on the com...

A generalization of the Gell-Mann–Low Theorem is applied to bound state calculations in Yukawa theory. The resulting effective Schrödinger equation is solved numerically for two-fermion bound states with the exchange of a massless boson. The complete low-lying bound state spectrum is obtained for different ratios of the constituent masses. No abnormal solutions are found. We show the consistenc...

The present paper is based on the assumption that heavy quarks bound states exist in the Standard Model (SM). Considering New Bound States (NBS) of topanti-top quarks (named T-balls) we have shown that: 1) there exists the scalar 1S–bound state of 6t + 6t̄; 2) the forces which bind the top-quarks are very strong and almost completely compensate the mass of the twelve top-anti-top-quarks in the s...
