Some Important Contributions:

"Experimental Observation of a Heavy Particle J," Phys. Rev. Lett. 33: 1404 (1974), with J.J. Aubert, U. Becker, P.J. Biggs, J. Burger, M. Chen, G. Everhart, P. Goldhagen, J. Leong, T. McCorriston, T.G. Rhoades, M. Rohde, S.C.C. Ting.

    Discovery of the J/ particle which is a bound state of charm and anticharm quarks. This discovery wa an important step leading to understanding of the fundamental structure of matter in terms of leptons and quarks.

"A Method of Three-jet Analysis in e+ e- Annihilation," Z. Phys. C 2: 107 (1979), with George Zobernig.
    Important analysis enabling identification of gluon jet events which are fundamental processes in quantum chromodynamics. This method was used in the following publication.

"Evidence for Planar Events in e+ e- Annihilation at High Energies," Phys. Lett. B 86: 243 (1979) with TASSO Collaboration, R. Brandelik et al..
    Events are explained by e+ e- annihilation into a quark-antiquark pair with radiation of a gluon - gluon radiation is a fundamental process of quantum chromodynamics (QCD).  For a detailed explanation see "The First Evidence for Three-jet Events in e+ e- Collisions at Petra - First Direct Observation of the Gluon," Proceedings of the International Europhysics Conference on High Energy Physics, 1995, Brussels, Belgium. This was a talk given by Professor Wu at the award to her and Paul Söding, Björn Wiik, and Günter Wolf of the 1995 European Physical Society High Energy and Particle Physics Prize.

"Determination of the Number of Light Neutrino Species", Phys. Lett. B 231: 519 (1989) with ALEPH Collaboration, D. DeCamp et al..
    Determination that the number of light neutrino species is three.

"Evidence for b baryons in Z decays", Phys. Lett. B 278: 209 (1992) with ALEPH Collaboration, D Decamp et al..
    Discovery of baryon composed of d,  s, and b quarks - the Lambdab.

"Observation of the semileptonic decays of Bs and Lambdab hadron at LEP," Phys. Lett. B 294: 145 (1992) with ALEPH Collaboration, D. Buskulic et al..
    First discovery by the Wisconsin Group of Sau Lan Wu in the ALEPH collaboration of the Bs meson by direct observation.
