Large tree-level {ital CP} violation in {ital e}{sup +}{ital e}{sup {minus}}{r_arrow}{ital t{bar t}H}{sup 0} in the two-Higgs-doublet model
- Physics Department, Technion-Israel Institute of Technology, Haifa 32000 (Israel)
We find a large {ital CP} violation effect within the two-Higgs-doublet model for the reaction {ital e}{sup +}{ital e}{sup {minus}}{r_arrow}{ital t}{bar {ital t}}{ital H}{sup 0} at future linear colliders. The {ital CP} asymmetry arises already at the tree level as a result of interference between diagrams with {ital H}{sup 0} emission from {ital t} (and {bar {ital t}}) and its emission from a {ital Z}{sup 0} and can be about 10{endash}20 {percent}. In the best case one needs a few hundred {ital t{bar t}H}{sup 0} events to observe {ital CP} violation at the 3{sigma} level. {copyright} {ital 1996 The American Physical Society.}
