In this note we estimate the sensitivity to these interactions at the high luminosity phase of the LHC and a future 100 TeV $pp$ collider (FCC-hh). For the LHC, the expected limits on $t \\to uZ / u\\gamma $ branching ratios from $Zt$ and $\\gamma t$ production will reach the $10^{-5}$ level, one order of magnitude better than the existing projections for $t \\to uZ$ from $t \\bar t$ production. For the FCC-hh, the limits on $t \\to uZ / u\\gamma$ could reach an impressive sensitivity at the $10^{-6}$ level, with limits on $t \\to cZ / c\\gamma$ at the $10^{-5}$ level.", "revisions": [ { "version": "v1", "updated": "2017-09-12T17:59:11.000Z" } ], "analyses": { "keywords": [ "production", "high luminosity phase", "interactions", "magnitude better", "excellent probe" ], "note": { "typesetting": "LaTeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
