|Title:||Observation of a New X-b State in Radiative Transitions to Y(1S) and Y(2S) at ATLAS||Authors:||Aad, G.

|Keywords:||[No Keywords]||Issue Date:||2012||Publisher:||Amer Physical Soc||Abstract:||The chi(b)(np) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider at root s=7 TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4 fb(-1), these states are reconstructed through their radiative decays to Y(1S,2S) with Y ->mu(+)mu(-). In addition to the mass peaks corresponding to the decay modes chi(b)(1P,2P)-> Y(1S)gamma, a new structure centered at a mass of 10.530 +/- 0.005(stat)+/- 0.009(syst) GeV is also observed, in both the Y(1S)gamma and Y(2S)gamma decay modes. This structure is interpreted as the chi(b)(3P) system.||URI:||https://doi.org/10.1103/PhysRevLett.108.152001
