Top-quark Yukawa coupling with a dimension-6 operator

Ya-Juan Zheng

We extend the standard top-quark Yukawa coupling with a dimension-6 operator in order to accommodate a CP violating complex phase with manifest gauge invariance. This leads to a ne…

$μ^{-} μ^{+} \to ν_{μ} ν ˉ_{μ} t t ˉ H$ amplitudes in the Feynman-diagram gauge

Ya-Juan Zheng

We study the process $μ^{-} μ^{+} \to ν_{μ} ν ˉ_{μ} t t ˉ H$ with complex CP violating $tt H$ couplings in the SMEFT with a dimension-6 operator. When the amplitudes are expressed in the…
