Description

We study the production of a narrow structure $X^{\pm}(5568)$ decaying to $B^0_s\pi^{\pm}$ produced in $10.4\ \rm fb^{−1}$ of $p\bar p$ collisions recorded by the D0 detector at the Fermilab Tevatron collider at $\sqrt s=1.96\ $TeV. We report evidence for the production of $X^{\pm}(5568)$ using the semileptonic mode $B^0_s \to \mu^{\mp}D_s^{\pm}X$ with $ D_s^{\pm}\to\phi\pi^{\pm}$. The results are consistent with the previous measurements by D0 of the production of $X^{\pm}(5568)$ using the hadronic decay $B^0_s \to J/\psi\phi$. The mass and width of this state are measured using a combined fit of the hadronic and semileptonic data.
