New Bound States of Heavy Quarks at LHC and Tevatron

Abstract

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 top–antitop quarks (named T-balls) we have shown that: (1) there exists the scalar 1S-bound state of [Formula: see text]; (2) the forces which bind the top-quarks are very strong and almost completely compensate the mass of the twelve top–antitop-quarks in the scalar NBS; (3) such strong forces are produced by the Higgs–top-quarks interaction with a large value of the top-quark Yukawa coupling constant gt≃1. Theory also predicts the existence of the NBS [Formula: see text], which is a color triplet and a fermion similar to the t'-quark of the fourth generation. We have also considered the "b-quark-replaced" NBS, estimated the masses of the lightest fermionic NBS: M NBS ≳300 GeV , and discussed the larger masses of T-balls. We have developed a theory of the scalar T-ball's condensate and predicted the existence of three SM phases. Searching for heavy quark bound states at the Tevatron and LHC is discussed. We have constructed the possible form-factors of T-balls, and estimated the charge multiplicity coming from the T-ball's decays.

Diphoton decay of the Higgs boson and new bound states of top and antitop quarks

“…Indeed we imagine that the SM could turn out to be valid up to essentially the Planck scale, apart from the existence of some right-handed neutrinos at a see-saw scale of around 10 12 GeV. This scenario of course suffers from the hierarchy problem of why the ratio of the Planck scale to the electro-weak scale is so huge.…”

“…where a B is the radius of the Bohr Hydrogen-atom-like bound state S, in which we approximate the interaction of each top quark by a central 1/r potential (neglecting the Higgs mass) while only half of the other 11 particles 5 are present in the "nucleus" [10]. The variable z denotes the position coordinate in an axial coordinate system.…”

“…Previously we have speculated [1][2][3][4][5][6][7][8][9][10][11][12] that 6 top + 6 anti-top quarks should be so strongly bound that the bound states, having masses small compared to the total mass of 12 top quarks, would effectively function as elementary particles to first approximation. In this case they can be added into loop calculations as "new" particles in the theory and seen, if produced at LHC, as resonances.…”

F(750), we miss you as bound state of 6 top and 6 antitop

“…In pure Standard Model we suggest there being three by "multiple point principle" low energy density vacua, "present", "condensate" and "high field" vacuum. We fit the mass of the in our picture since long speculated bound state [69,70,71,72,74,75,76,77,78,79,80,81,82,83,8] of six top and six anti top quarks in three quite independent ways and get remarkably within our crude accuracy the same mass in all three fits! The new point of the present article is to estimate the bound state mass in what we could call a bag model estimation.…”

“…We have long worked on the speculation, that six top and six anti top quarks due to mainly the rather large value of the top-yukawa coupling g t and thus to Higgs boson exchange gets bound so strongly to each other, that a bound state with a mass appreciably lower than the sum of the masses of 12 top-quaks is formed [9,69,70,71,72,74,75,76,77,78,79,80,81,82,83,8,6]. In the present article we shall put forward an attempt to estimate the mass of this bound state by setting up a kind of bag-model ansatz for the bund state system.…”
