Abstract:

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 X b →π + π − ϒ(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 states is found, and upper limits are set on the product of the X b cross section and branching fraction, relative to those of the ϒ(2S), at the 95% confidence level using the CL S approach. These limits range from 0.8% to 4.0%, depending on mass. For masses above 10.1 GeV, the expected upper limits from this analysis are the most restrictive to date. Searches for production of the ϒ(1 3 D J ), ϒ(10860), and ϒ(11020) states also reveal no significant signals. © 2014 The Authors
