LHC bounds on coloured scalars

Understand

We analyze the constraints on coloured scalar bosons imposed by the current LHC data at $\sqrt{s}=13$ TeV.

• Specifically, we consider an additional electroweak doublet of colour-octet scalars, satisfying the principle of Minimal Flavour Violation in order to fulfill the stringent experimental limits on flavour-changing neutral currents.
• We demonstrate that coloured scalars with masses below 800 GeV are already excluded, provided they are not fermiophobic.
