Dimension-six top-quark Higgs-boson interaction and its effect in collider phenomenology
Dimension-six top-quark Higgs-boson interaction and its effect in collider phenomenology
Measurement of the Yukawa interaction between the top quark and the Higgs boson should be useful to clarify the mechanism of fermion mass generation. We discuss the impact of nonstandard interactions characterized by dimension-six operators on the effective top Yukawa coupling. The cross section of the process ${e}^{\ensuremath{-}}{e}^{+}\ensuremath{\rightarrow}{W}^{\ensuremath{-}}{W}^{+}\ensuremath{\nu}\overline{\ensuremath{\nu}}\ensuremath{\rightarrow}t\overline{t}\ensuremath{\nu}\overline{\ensuremath{\nu}}$ is calculated …
