Section 5: Discovery Potential: Supersymmetry

This section presents 5σ discovery sensitivity projections of the several SUSY searches by CMS to the 14 TeV 300 fb-1 scenario. These projections are performed by scaling the luminosity and taking into account the change of cross section with higher energy accordingly. The projections are made based on 8 TeV Monte Carlo samples and without optimizing the selections for searches at higher energies and higher luminosities. In “Scenario A” the signal and background yields, and the uncertainty on the background, are scaled by the ratio of the luminosities (20 fb-1 for 8 TeV and 300 fb-1 for 14 TeV) and by the ratio of the cross sections for signal and background. More details can be found in the paper.

pdf, png Next-to-leading order cross sections for gluino-pair production, stop-pair (sbottom-sbottom) production, and chargino-neutralino production versus the mass of the pairproduced SUSY particles. The chargino-neutralino production cross section is presented for common m(χ1+-) = m(χ10) masses.
pdf, png (top) The simplified model topology for gluino production, where the gluinos decay to two top quarks and an LSP each, and (bottom) the projected 5σ discovery reaches for this model.

This projection is based on the search in events with a single lepton, multiple jets, and b-tags: CMS-PAS-SUS-13-007 [ CDS ].
