Suppressed interference in the SMEFT and related topics

The interference between the SM and the dimension-six operators in the SMEFT framework are often suppressed. I will present some observables which can lift the suppression when it is due to the phase space and show how to quantify their efficiency to revive the interference. The interference resurrection is also essential to have higher correction under control. Finally, I would like to show that, while interference suppression for some processes happens for all the dimension-six operators, it is not the case for the dimension-eight operators.
