Probing the CP properties of top Yukawa coupling at an e + e − collider
Abstract We study consequences of CP violation in the htt¯ $$ ht\overline{t} $$ Yukawa coupling through the process e+e−→h125tt¯ $$ {e}^{+}{e}^{-}\to h(125)t\overline{t} $$. The helicity amplitudes are calculated in the tt¯ $$ t\overline{t} $$ rest frame, where the initial e + e − current and the fi...
