A search for radiative decay of B^0_s mesons to orbitally excited K^+K^- states is performed using proton proton collisions recorded by the \mbox{LHCb}\xspace experiment, corresponding to an integrated luminosity of 9~fb^{-1}. The dikaon spectrum in the mass range m_{KK}<2400~{\ensuremath{\,\text{Me\kern -0.1em V\!/}c^2}\xspace} is dominated by the \phi(1020) resonance that accounts for... Show more
