Search for the suppressed decays $B^{+}\to K^{+}{K}^{+}\ddot{I}{€}^{-}$ and $B^{+}\to \ddot{I}{€}^{+}\ddot{I}{€}^{+}{K}^{-}$

Abstract

A search is made for the highly-suppressed B meson decays $B^{+}\to K^{+}{K}^{+}\ddot{I}{€}^{-}$ and $B^{+}\to \ddot{I}{€}^{+}\ddot{I}{€}^{+}{K}^{-}$ using a data sample corresponding to an integrated luminosity of 3.0 $f{b}^{-1}$ collected by the LHCb experiment in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV. No evidence is found for the decays, and upper limits at 90\% confidence level are determined to be $\mathcal{B}(B^{+}\to K^{+}{K}^{+}\ddot{I}{€}^{-})<1.1\times 10^{-8}$ and $\mathcal{B}(B^{+}\to \ddot{I}{€}^{+}\ddot{I}{€}^{+}{K}^{-})<4.6\times 10^{-8}$.
