Search for gluinos inwards events amongst an isolated lepton, jets together with missing transverse momentum at \(\sqrt{s} = 13\TeV\) amongst the ATLAS detectorin which gluino pairs were searched inwards in conclusion states amongst MET, many jets, together with a unmarried lepton. There were 6 signal regions. The last, 6th one, showed a mild exactly interesting excess. \(2.5\pm 0.7\) events were expected amongst a muon (thanks, Bill), exactly viii events were observed.
The excess looks intriguing when it's visualized on Figure 6.
The plot has 2 parts:
The observed thick ruby-red exclusion business is to a greater extent than frequently than non similar to the dashed dark expected exclusion line. But on the upper picture, at that spot is a clear "downward tooth" of the ruby-red business around the gluino volume of \(1200-1300\GeV\) together with the lightest neutralino volume around \(400-600\GeV\), potentially properties of particles that may be according to this hint.
On the 2nd diagram, the excess looks similar an isle amongst \(m_{\tilde g} \sim 1250\GeV\) together with the ratio of 2 volume differences (lightest chargino minus outset lightest neutralino OVER gluino minus lightest neutralino) equal to \(0.75\) or so. However, the plot isn't quite showing the neighborhood of the nigh interesting values indicated yesteryear the upper plot because inwards the lower plot, the lightest neutralino is assumed to weigh \(60\GeV\).
The island-like sort of the exclusion business on the lower motion-picture demo is interesting, nevertheless. Note that this is what the exclusion lines human face similar when all the incorrect values of the volume are excluded together with the right volume is discovered. In this sense, the lower motion-picture demo could already live a sketch of a regain paper.
At whatever rate, if you lot larn through the LHC category or search for a gluino on this blog, I intend you lot volition concur that it's far from the outset hint of a gluino unopen plenty to \(1200\GeV\) together with a lightest neutralino inwards the \(600\GeV\) category. I am extremely far from whatever degree of certainty that the gluino has to live establish nigh these masses exactly if you lot offering me 100-to-1 odds similar Jester did, I volition happily brand the bet in i trial again (or increase the existing one, if you lot wish).
