Ultraboosted $Zt$ and $\gamma t$ production at the HL-LHC and FCC-hh

Searches for anomalous Zt and $\gamma t$ production provide an excellent probe of flavour-changing top interactions when the energies considered are very large. 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 (FC...

description Searches for anomalous Zt and $\gamma t$ production provide an excellent probe of flavour-changing top interactions when the energies considered are very large. 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 \rightarrow 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 $t \rightarrow uZ$ from $t {\bar{t}}$ production. For the FCC-hh, the limits on $t \rightarrow uZ / u\gamma $ could reach an impressive sensitivity at the $10^{-6}$ level, with limits on $t \rightarrow cZ / c\gamma $ at the $10^{-5}$ level.
