Abstract

Flavour changing neutral currents are suppressed in the Standard Model, making them a prime avenue to search for new physics. Although several measurements of the decay $B^{0}\to{}K^{\ast{}0}\mu^{+}\mu^{-}$ have shown deviations from the Standard Model expectations, long-distance contributions may be imitating new physics. Here, the first amplitude analysis of $B^{0}\to{}K^{\ast{}0}\mu^{+}\mu^{-}$ is carried out to try and discern such effects.
