We show how single top production at the LHC can be used to discover (and
characterize the couplings of) B' quarks, which are an essential part of many
natural models of new physics beyond the Standard Model. We present the B'
effective model and concentrate on resonant production via a colored anomalous
magnetic moment. Generally, B's preferentially decay into a single top quark
produced in association with a W boson; thus, this production process makes
associated single top production essential to B' searches at the LHC. We
demonstrate the background processes are manageable and the signal cross
section is sufficient to yield a large signal significance even during the 7
TeV LHC run. Specifically, we show that B' masses of 700 GeV or more can be
probed. Moreover, if a B' is found, then the chirality of its coupling can be
determined. Finally, we present signal cross sections for several different LHC
energies.Comment: 19 pages, 7 figures, 1 tabl
