As a result, experimental physicists will use the Cornell results and theorists will use lattice-QCD techniques to independently determine the contributions from the particle commotion inside of D mesons.
Because the results of the experiments should be available by next summer, some lattice-QCD theorists are rushing to apply their new methods to D mesons and to publish predictions of decay rates and other parameters that the Cornell-based team will measure.
