Observation of a new χ(b) state in radiative transitions to Υ(1S) and Υ(2S) at ATLAS.

Observation of a new χ(b) state in radiative transitions to Υ(1S) and Υ(2S) at ATLAS.

The χ(b)(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider at sqrt[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...
