Search for the X-b and other hidden-beauty states in the pi(+)pi(-)gamma(1S) channel at ATLAS

This Letter presents a search for a hidden-beauty counterpart of the X(3872) in the mass ranges of 10.05-10.31 GeV and 10.40-11.00 GeV, in the channel Xb→π+π-ϒ{hooked}(1S)(→μ+μ-), using 16.2 fb-1 of s=8 TeV pp collision data collected by the ATLAS detector at the LHC. No evidence for new narrow stat...
