Abstract
The relative abundance of the three decay modes , , and produced in 7 TeV collisions at the LHC is determined from data corresponding to an integrated luminosity of . The branching fraction of is found to be . The ratio of fragmentation fractions is determined through the relative abundance of to and , leading to , where the uncertainties are statistical, systematic, and theoretical, respectively.
