Quantum bull's-eye: particle-mass prediction hits the mark by Weiss, P. / Science News 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. Starting from square one: the intricate behaviors of quarks may ... by Weiss, Peter Ulrich / Science News for example, could be a combination of a strange quark, an up quark and two anti-down quarks, or a combination of two D mesons.
