Search for the Exotic Meson X (5568 ) with the Collider Detector at Fermilab

A search for the exotic meson X (5568 ) decaying into the B_s⁰π^± final state is performed using data corresponding to 9.6 fb^-1 from p p ¯ collisions at √{s }=1960 GeV recorded by the Collider Detector at Fermilab. No evidence for this state is found and an upper limit of 6.7% at the 95% confidence level is set on the fraction of B_s⁰ produced through the X (5568 )→B_s⁰π^± process.
