Cernette: A Saltation Acre Of 2 \(Z'\)-Bosons?

TV: John Oliver gave a totally sensible 20-minute tirade explaining why "scientific report says" stories inwards the media are generally bullšit.

I am giving a pop speak on LIGO inwards xc minutes as well as Tristan du Pree has offered me a distraction via Twitter. How create yous locomote distracted if yous intend almost LIGO equally good much? Yes, yesteryear hearing almost the LHC:

Did yous let out already a adept model for a possible \(375/750/1500\) tower of \(Z\gamma/\gamma \gamma\)?

Well, I didn't, I wrote him: it seemed increasingly clear to me that the invariant masses inwards the \(Z\gamma\) as well as \(\gamma\gamma\) decays should amend live the same. So the numerological explanation of the coincidence doesn't work.

But as well as thus I decided that I haven't carefully plenty investigated a loophole that could explicate why the \(\gamma\gamma\) indicate isn't observed close \(375\GeV\): the Landau-Yang theorem. Influenza A virus subtype H5N1 massive spin-one boson cannot decay to ii identical massless spin-one bosons – or, if yous wish, a \(Z\)-boson or \(Z'\)-boson cannot decay to ii photons.




The argue for or the proof of the theorem? Well, there's no trilinear locomote of the iii polarization vectors \(\vec \epsilon_{1,2,3}\) that may also depend on the massless particle's momentum \(\vec k\) but that is also symmetric nether the telephone substitution of the ii concluding photons.




That seems to live the solely possible explanation of the absence of the \(\gamma\gamma\) indicate at \(375\GeV\) given the supposition that the excesses of \(Z\gamma\) at \(375\GeV\) are existent novel physics. So if that's the case, in that place has to live a novel \(Z'\)-boson at \(375\GeV\). Or possibly fifty-fifty a composite particle, such equally a toponium, could live OK?

And if the coincidence \(750/2=375\) is to a greater extent than than simply a coincidence, as well as thus the \(750\GeV\) cernette should amend live a saltation soil of the ii \(375\GeV\) \(Z'\)-bosons. Probably a tightly saltation state, indeed, but the large width observed peculiarly yesteryear ATLAS could potentially live explained yesteryear this composite grapheme of the object.

I realize that the interactions felt yesteryear the novel \(Z'\)-boson would convey to live immensely strong as well as it in all likelihood doesn't piece of occupation but I am running out of fourth dimension thus I expression roughly commenters to enjoin me whether it could work.
