The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

There are theoretical speculations that the top quark may have different properties from that predicted by the standard model. We use an effective Lagrangian technique to model such a non-standard top quark scenario and study its effects on the electroweak baryogenesis, low and high energy physics.

When all the non-SM degrees of freedom are heavy, all such models can be reduced to SMEFT [ref] , and we identify the following top quark Yukawa sector [ref]

CP-violating top-Higgs coupling in SMEFT · Introduction · 0.80
It has been suggested [ref] that new physics may appear as higher-dimensional, nonrenormalisable operators added to the Standard Model Higgs scalar potential, getting around the constraints posed by present experimental bounds on the Higgs mass and providing additional sources of CP violation.
