Yukawa coupling deviations from four-quark interactions
Sophie Renner, Benjamin Smith
New physics generating four-quark interactions can be difficult to detect at the LHC, especially if it does not couple to first generation quarks. We investigate the possible role…

The Price of a Large Electron Yukawa Modification
Lukas Allwicher, Matthew McCullough, Sophie Renner +2
The theoretical implications of an electron Yukawa modification are considered in the context of a possible Higgs pole run at FCC-ee, aimed at bounding this coupling. We start from…

Diagonalising the LEFT
Sophie Renner, Benjamin Smith, Dave Sutherland
We organise the four-fermion vector current interactions below the weak scale -- i.e., in the low energy effective field theory (LEFT) -- into irreps of definite parity and …
