Search for the B s0 → η′ϕ decay

Abstract

A search for the charmless Bs0 → η′ϕ decay is performed using pp collision data collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. No signal is observed and upper limits on the Bs0 → η′ϕ branching fraction are set to 0.82 × 10−6 at 90% and 1.01 × 10−6 at 95% confidence level.[Figure not available: see fulltext.].
