  • Dr. Thomas Junk, CERN, Searches for the Higgs Boson at LEP
    light enough to have been produced at LEP in its final year of operation A review is given of the motivation for the searches improvements made to the LEP accelerator and the results of the searches for the Standard Model Higgs boson A lower limit of mH 113 5 GeV is obtained by combining the results of the four experiments together and an excess of 2 9 sigma is observed

  • Dr. Alex Filippenko, UC Berkeley, Einstein's Biggest Blunder? The Case for an Accelerating Universe
    the Milky Way The light curves of high redshift z 0 3 1 supernovae are stretched in a manner consistent with the expansion of space similarly their spectra exhibit slower temporal evolution by a factor of 1 z than those of nearby supernovae Our most important conclusion is that the expansion of the Universe is accelerating perhaps due to the presence of vacuum energy also referred to as Lambda or Einstein s cosmological constant Thus Einstein seems to have been right after all but for the wrong reason and with the incorrect numerical value for Lambda We derive a current dynamical age of 14 1 2 billion years for the Universe consistent with the ages of globular star clusters Moreover combining our results with existing measurements of the cosmic microwave background radiation we find a best fit for the normalized matter density and vacuum energy density in the Universe of about 0 3 and 0 7 respectively With a sum close to unity this agrees with the value predicted by most inflationary models for the evolution of the Universe and indicates that the Universe is flat Euclidean geometry on large scales A number of systematic effects dust evolution might be

    of old stars spun up by accretion is limited by an instability driven by gravitational waves If so the emitted waves may be observable by gravitational wave detectors with the sensitivity of LIGO II A review of these hopeful results is followed by a more sober listing of accompanying caveats Audio for this talk requires sound hardware and RealPlayer or RealAudio by RealNetworks Begin continuous audio for the whole talk

  • Dr. Mark Newman, Center for Applied Mathematics, Cornell University & Santa Fe Institute, The Structure of Scientific Collaboration Networks
    Assuming two scientists to be connected if they have written a paper together we have analyzed a number of large computer databases of publications to construct explicit networks and used these networks to answer questions like Who are the best connected scientists in the world Which scientists have the strongest collaborations Which scientists connect most others together HOw many degrees of separation are there between scientists on average And what

  • Dr. Steven Girvin, ITP & Indiana University, Physics of "Which Layer?" Uncertainty
    quantum state in which we are uncertain which of the layers they are in Such broken symmetry or interlayer phase coherent states are energetically favored by the strong Coulomb interactions among the electrons and lead to several different remarkable phenomena In particular a close analog of the superconducting Josephson effect has recently been observed experimentally An elementary introduction to these remarkable developments will be presented Audio for this talk requires
