Observation of a new χ b state in radiative transitions to Y(1S) and Y(2S) at ATLAS
The χ b (nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider at √s=7TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4fb - 1, these states are reconstructed through their radiative decays to Υ(1S,2S) wi...
