Description
Charmless $b$-hadron decays are good probes to test the Standard Model and search for New Physics. Of particular interest are the $B^0_s$ decays to final state with light resonances ($\eta$, $\eta^{\prime}$ or $\phi$) that can be used for time-dependent CP violation studies. The ``golden'' $B^0_s \to \phi\phi$ mode has already been used by LHCb to measure the CP-violating phase difference between the $B^0_s$ mixing amplitude and the $b\to s\bar{s}s$ decay amplitude. We present the results of the search for the yet unobserved $B^0_s \to \eta^{\prime}\phi$ decays using the full data sample from LHCb Run1, as well as prospects for the other modes of this family using the LHCb Run2 data.
