AU - Aguilar Saavedra, Juan Antonio AU - Atlas Collaboration PY - 2012 UR - http://hdl.handle.net/10481/62813 AB - The χb(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider at √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...
