Precision Flavour Physics with $B\to K\nu \bar{\nu }$ and $B\to K{l}^{+}{l}^{-}$

M. Bartsch, M. Beylich, G. Buchalla +1

We show that a combined analysis of $B\to K\nu \bar{\nu }$ and $B\to K{l}^{+}{l}^{-}$ allows for new physics tests practically free of form factor uncertainties. Residual theory errors are at the…
