Search for single b ⁎ -quark production with the ATLAS detector at √s=7 TeV

The results of a search for an excited bottom-quark b ⁎ in pp collisions at s=7 TeV, using 4.7 fb −1 of data collected by the ATLAS detector at the LHC are presented. In the model studied, a single b ⁎ -quark is produced through a chromomagnetic interaction and subsequently decays to a W boson and a...
