Systematic errors

Tab. 3 and 4 summarize the sources of the systematic uncertainties on the branching ratio and the charge asymmetry.

Table 3: Contributions to the systematic uncertainty on the branching ratio.

SYSTEMATIC	ERROR [%]
$B^{\pm } \rightarrow \phi K^{\pm }$ yield	3.0
$B^{\pm} \rightarrow J/\psi K^{\pm}$ yield	3.3
$\varepsilon_{\mu\mu K}/\varepsilon_{KKK}$	1.5
$\langle\varepsilon_{\mu}\rangle$	2.6
$\varepsilon_{R_{iso}}$	1.4
Particle dependent XFT efficiency	3.3
acceptance $\varphi$ dependance due to COT ageing	0.3
$\chi^{2}_{xy}$ cut efficiency	3.0
$B\!R(J/\psi\to\mu\mu)$	1.2
$B\!R(\phi\to KK)$	1.7
TOTAL	7.4
