Search for a Structure in the $B_s^0{\pi }^{\pm }$ Invariant Mass Spectrum with the ATLAS Experiment

ATLAS Collaboration

A search for the narrow structure, $X(5568)$, reported by the D0 Collaboration in the decay sequence $X\to B_s^0{\pi }^{\pm }$, $B_s^0\to J/\psi \varphi$, is presented. The analysis is based on a…
