 | The number of independent SMEFT operators up to dimension 15~\cite{Henning:2015alf}. Points joined by the lower (upper) solid line are for one (three) generations of fermions. Dashed lines are to guide the eye to the growth of the even and odd dimension operators. |
 | Computing the flavor representations for the field content $q^3 l B_L$. See the text for details. |
 | $B_0$ coefficient as a function of the dilepton invariant mass. |
 | Statistical significance of the $B_0$ angular dependence as a function of the dilepton invariant mass. |
 | 95\% CL intervals for the dimension-6 four-fermion operators that interfere with the SM. Both the limits obtained by considering only $\mathcal O(1/\Lambda^2)$ effects, as well as those including the $\mathcal O(1/\Lambda^4)$ corrections, are shown. |
