Summary of the projected HL-LHC limits on the light quark Yukawa couplings, including charm.
\it Marginalised 95\% CL projected sensitivities for LHC, HL-LHC, HE-LHC, and combined HL/HE-LHC in increasingly darker shades of red. The vertical axis gives the reach to the scale of new physics divided by the dimensionless Wilson coefficient, in units of \UTeV.
\it Current constraints on dimension-6 operators. The orange and green bars are the marginalised and individual limits from Ref.~\cite{Ellis:2018gqa}, respectively. The analogous results of the HEPfit Collaboration~\cite{Ciuchini:2013pca, deBlas:2016ojx} for the case where only one operator is switched on at a time are shown in blue.
