BSM reach of rare charm decays, including the rising star ${\Lambda }_c\to p{\mu }^{+}{\mu }^{-}$

Hector Gisbert, Gudrun Hiller, Dominik Suelmann

We perform the first global fit of rare charm transitions using recent data on $D^0\to {\mu }^{+}{\mu }^{-}$, $D^{+}\to {\pi }^{+}{\mu }^{+}{\mu }^{-}$, ${\Lambda }_c\to p{\mu }^{+}{\mu }^{-}$ and $D^0\to {\pi }^{+}{\pi }^{-}{\mu }^{+}{\mu }^{-}$ decays, including angul…
