Search for the $B^{0}_{s} \to \eta^{\prime}\phi$ decay

TL;DR

This paper reports a search for the rare decay $B^{0}_{s} o ext{eta'} ext{phi}$ using LHCb data, setting upper limits on its branching fraction due to no observed signal.

Contribution

First search for the $B^{0}_{s} o ext{eta'} ext{phi}$ decay, establishing upper limits on its branching fraction with LHCb data at 7 and 8 TeV.

Findings

No signal observed for the decay.

Upper limits on branching fraction set at $0.82\times 10^{-6}$ (90%) and $1.01\times 10^{-6}$ (95%).

Abstract

A search for the charmless $B^{0}_{s} \to \eta^{\prime}\phi$ 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 $B^{0}_{s} \to \eta^{\prime}\phi$ branching fraction are set to $0.82\times 10^{-6}$ at $90\%$ and $1.01\times 10^{-6}$ at $95\%$ confidence level.
