English AbstractA search for the narrow structure, x(5568), reported by the do collaboration in the decay sequence x -> b-s(0) pi +/-, b-s(0) -> j/psi phi, is presented. the analysis is based on a data sample recorded with the atlas detector at the lhc corresponding to 4.9 fb(-1) of pp collisions at 7 tev and 19.5 fb(-1)at 8 tev. no significant signal was found. upper limits on the number of signal events, with properties corresponding to those reported by do, and on the a production rate relative to b-s(0) mesons, rho x, were determined at 95% confidence level. the results are n(x) < 382 and rho x <0.015 for b-s(0) mesons with transverse momenta above 10 gev and n(x) < 356 and rho(x) < 0.016 for transverse momenta above 15 gev. limits are also set for potential b-s(0) pi(+) resonances in the mass range 5550 to 5700 mev.
