A review of recent precision measurements of the electromagnetic form factors of the mesons, pion and kaon, and the hyperons, $Lambda^0$, $Sigma^0$, $Sigma^+$, $Xi^-$, $Xi^0$, $Omega^-$, at large timelike momentum transfers is presented. Evidence is found for diquark correlations in $Lambda^0$, $Sigma^0$ hyperons.
Using $e^+e^-$ annihilation data taken at the CESR collider with the CLEO-c detector, measurements of hyperon pair production cross sections and elastic and transition electromagnetic form factors have been made at the charmonium resonances: $psi(2S)
At the Tevatron Collider at Fermilab, a large number of top quarks have been produced in the ongoing run. The CDF and DZero collaborations have made first measurements of the ttbar cross section in several decay channels, and have measured the top qu
One of the open issues in evaluations of the contribution from hadronic light-by-light scattering to the anomalous magnetic moment of the muon $(g-2)_mu$ concerns the role of heavier scalar, axial-vector, and tensor-meson intermediate states. The cou
We present a review of measurements of alpha_S. The individual measurements are discussed and intermediate averages for classes of related measurements are found. The final average is built using the intermediate values. Correlations are treated cons
We calculate, in the continuum limit of quenched lattice QCD, the matrix elements of the heavy-heavy vector current between heavy-light pseudoscalar meson states. We present the form factors for different values of the initial and final meson masses
