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

Abstract

We consider the constraints, provided by the LHC results on Higgs boson decay into 2 photons and its production via gluon fusion, on the previously proposed Standard Model (SM) strongly bound state S of 6 top quarks and 6 anti-top quarks. A correlation is predicted between the ratios κ γ and κ g of the Higgs diphoton decay and gluon production amplitudes respectively to their SM values. We estimate the contribution to these amplitudes from one loop diagrams involving the 12 quark bound state S and related excited states using an atomic physics based model. We find two regions of parameter space consistent with the ATLAS and CMS data on (κ γ , κ g ) at the 3 sigma level: a region close to the SM values (κ γ = 1, κ g = 1) with the mass of the bound state m S > 400 GeV and a region with (κ γ ∼ 3/2, κ g ∼ −3/4) corresponding to a bound state mass of m S

New results at LHC confirming the vacuum stability and Multiple Point Principle

“…Here p 1 + p 2 = p 3 + p 4 . The coupling constant between the three scalar particles SSH (see [82]) is:…”

“…In previous Refs. [ [54][55][56][57] (see also [58][59][60][61][62][63][64][65][66][67]), we and collaborators have speculated that 6 top + 6 anti-top quarks should be so strongly bound that the bound states would effectively function at low energies as elementary particles and can be added into loop calculations as new elementary particles in the theory, and seen, if produced, as resonances. But because of their at the end composite nature they would deviate from a fully fundamental particles by having formfactors cutting off their interactions for high four momenta.…”

“…the Standard Model). In realizing the picture, which we suggest in connection with this new law of nature, we further need to have that there exists an extremely strongly bound state [21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36] of six top plus six antitop quarks, and thus our main points are:…”

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.…”
