Description
$SU(2)_L$-invariance links charged dilepton $\bar{q}\,q^\prime\,\bar{\ell}\,\ell$ and dineutrino $\bar{q}\,q^\prime\,\bar{\nu}\,\nu$ couplings. This connection can be established using SMEFT and holds if only SM-like left-handed light neutrinos are present. It allows to perform complementary experimental tests of lepton universality and charged lepton flavor conservation with flavor-summed dineutrino observables. The phenomenological implications are discussed in detail for the branching ratios of rare charm decays $c \to u\,\nu\bar\nu$, such as $D^+\to\pi^+\,\nu\bar\nu$, and rare $B$ decays $b \to q \,\nu \bar \nu$ with $q=d,s$ decays.
