Findings

New CP-odd operator at leading order.

Potential explanation for flavour anomalies.

Modified predictions for Delta F=1 and Delta F=2 processes.

Abstract

We develop a variant of the Minimal Flavour Violation ansatz for the case of a strongly interacting heavy-Higgs boson sector. The tower of effective operators differs from that for a Higgs system in the linear regime, and the new operators obtained at leading order include a CP-odd one. We investigate the impact of these operators on Delta F=1 and Delta F=2 observables, demonstrating that the non-linear scenario may have an interesting impact on the anomalies in present data.
