Here I desire to advert this Figure iii upper-left on Page 12 of ATLAS'
Search for Heavy Resonances Decaying to a \(W\) or \(Z\) Boson as well as a Higgs Boson inwards the \(q\bar q^{(\prime)} b\bar b\) Final State inwards \(pp\) Collisions at \(\sqrt sec = 13\TeV\) with the ATLAS DetectorYou may also aspect at Page xiv of the paper, Figure 4, where the Brazilian bands demo a broad 3-sigmaish excess nigh \(m_{Z'}\sim 3\TeV\).
The local significance is 3.3 sigma, the global significance is quantified every bit 2.2 sigma. So it's nowhere nigh a uncovering simply it's even as well as thence with the strongest deviations from the Standard Model that yous may regain inwards any novel LHC newspaper published inwards 2017 as well as thence far.
As the moving-picture demo embedded at the acme shows, virtually iii events were predicted inwards the interval of masses \(3,000-3,050\GeV\) simply 10 events were observed. Not bad. Correct me if yous tin read the numbers to a greater extent than accurately.
Clearly, if this apparent fluke were a existent signal, in that place could last a novel \(Z'\)-boson whose majority would last or as well as thence \(3\TeV\). That's amusing particularly because inwards September 2015, CMS announced an electron-positron pair whose invariant majority was \(m\sim 2.9\TeV\) – it was the unloosen energy record-breaker at that instant as well as a higher scorer than what was expected – as well as that 1 could accept been a novel \(Z'\)-boson, too.
I intend that the probability is some 98% that this ATLAS excess is a fluke simply if yous desire to last intrigued past times some existing – non yet outdated – deviations from the Standard Model, this could last 1 of your choices.
