Present and future constraints on top EW couplings

Understand

Various BSM models predict large deviations of the top electroweak couplings.

• Many examples will be given emphasizing the need for precise and model independent measurements of these couplings.
• Here I address the question of compatibility between theoretical predictions and the LEP/SLC/Tevatron constraints which, through loop effects, allow setting very significant constraints on these predictions.
• A Randall Sundrum inspired prediction will be discussed in more details.
