Bayesian analysis of $b\to s{\mu }^{+}{\mu }^{-}$ Wilson coefficients using the full angular distribution of ${\Lambda }_b\to \Lambda (\to p{\pi }^{-}){\mu }^{+}{\mu }^{-}$ decays

Thomas Blake, Stefan Meinel, Danny van Dyk

Following updated and extended measurements of the full angular distribution of the decay ${\Lambda }_b\to \Lambda (\to p{\pi }^{-}){\mu }^{+}{\mu }^{-}$ by the LHCb collaborations, as well as a new measurement of t…
