Production together with Decay of \(750\GeV\) land of half dozen superlative together with half dozen anti superlative quarksby 2 experienced physicists, Froggatt together with (co-father of string theory) Nielsen, that proposes that the \(750\GeV\) cernette could live on existent – together with it could live on a business office of the Standard Model. They've been talking nearly the boundary land (now proposed to live on the cernette) since 2003.
At that time, the particle was conjectured to live on then heavily boundary that it would live on a tachyon, \(m^2\lt 0\). I truly intend that composite tachyons can't be inward tachyon-free theories, tin they? (You amend believe that such a tachyonic particle is impossible because such a man-made Cosmos-eating tachyonic toplet would live on fifty-fifty worse than an Earth-eating strangelet LOL.)
The zodiac, a similarly foreign boundary land of 12 particles.
Unlike my numerologically driven weakly boundary states of novel particles, they suggest that the particle could live on a heavily boundary land of 12 superlative quarks inward total.
More precisely, they say that at that spot should live on half dozen superlative quarks together with half dozen superlative antiquarks inward the beast. The pose out half dozen is preferred because all \(2\times iii = 6\) arrangements of the spin-and-color are represented – both for quarks together with antiquarks. So this consummate listing could potentially brand a particle that is every bit stable every bit the atom of helium; or the helium-4 nucleus (the alpha-particle). The whole low-lying "shell" is occupied inward all these cases!
The binding unloosen energy could come upwards from the telephone commutation of the virtual Higgs quanta. Note that for the odd messenger spins, \(J=1,3,5,\dots\), i.e. for electromagnetism, the similar charges repel. For the \(J=2\) gravity, the similar charges (positive masses) attract. For \(J=0\), the similar charges must attract, too. Influenza A virus subtype H5N1 closer analysis of the signs inward the Dirac fermionic bilinears implies that the contrary sources of the Higgs champaign truly attract every bit good – then the "sign of the superlative quark" is ignored. An ironic side lawsuit of this dominion is that when a superlative quark-antiquark twosome is created, the full champaign they create jumps discontinuously. But dissimilar the electrical charge, the "charge sourcing the Higgs field" isn't conserved, then this boundary isn't contradicting anything.
Twelve superlative quarks convey the volume of \(12\times 173\GeV=2076\GeV\) then yous quest the interaction unloosen energy \(-1326\GeV\) to teach downwards to \(750\GeV\). There are \(12\times 11/ 2\times 1=66\) pairs of "tops" (or antitops) inward the proposed boundary state. If each of them contributes \(-20\GeV\) inward average, yous volition live on fine. But practise they contribute \(-20\GeV\) inward such bounds states? Cannot somebody simply calculate these things, e.g. closed to lattice QCD methods? Cannot ane come across this \(-20\GeV\) inward the toponium?
Both authors claim that \(pp\to SS\) where \(S\) is their 12-particle boundary land has the cross department of 0.2 pb together with 2 pb at \(8\TeV\) together with \(13\TeV\), respectively, which look proficient enough. The dominant decay modes should live on (in this order) \(S\to t\bar t,gg,hh,W^+W^-,ZZ,\) together with \(\gamma\gamma\). Given the depression condition of the diphoton, that doesn't expect likewise good, does it? It is pretty difficult to imagine how this complicated animate beingness decays at all – twelve particles convey to live on liquidated almost simultaneously. That exclusively occurs inward closed to real high order, doesn't it? I am truly surprised past times the high production cross department for the same reason.
But the simplicity makes the proposal attractive fifty-fifty if the absence of the Beyond the Standard Model physics could live on disappointing at the end.
