The previously reported observation of direct electrons produced in proton-proton collisions at the CERN ISR was extended to transverse moments, p*/ sub T/, as low as 0.6 GeV/c. The ratio of electron to pion cross sections seems to rise as p*/sub T/ is decreased. It increases by at most a factor of 2 between p*/sub T/ of 2 and 0.6 GeV/c. Results on the s-dependence of this ratio and on correlated charged particles are presented for p*/sub T/ greater than or equal to 1 GeV/c in another work. (auth).

The 50-year history of weak interaction since Fermi's pro posal of this coupling has been marked with striking direct inter plays between experimental results and theoretical understanding, e.g. the discoveries of neutrinos, parity violation, and CP vio lation. The recent discoveries of the quark hierarchy, the charm and the beauty, and the intermediate vector bosons W± and ZO have truly made a splendid page in the history of particle physics. It is the purpose of this conference to discuss the questions of quark and lepton generations and mixing, their relations to CP violation, and to ask the questions about what are inside the quarks and the leptons in view of the present and future exper imental situation. Dr. Ling-Lie Chau Brookhaven National Laboratory Upton, New York vii ACKNOWLEDGMENTS I would like to thank all the Advisory and Organizing Committee members for their advice and suggestions during the organization of the conference. The running of the conference could not have gone so smoothly without the help of many participants, I sincerely thank: L. Becker, F.J. Botella, S. Gentile, P. Le Comte, M.E. Machacek, L.

The charged particle spectrum at large transverse momentum (PT), dominated by hadrons originating from parton fragmentation, is an important observable for studying the properties of the hot, dense medium produced in high-energy heavy-ion collisions. The study of the modifications of the PT spectrum in PbPb compared to pp collisions at the same collision energy can shed light on the detailed mechanism by which hard partons lose energy traversing the medium. In this thesis, the transverse momentum spectra of charged particles in pp and PbPb collisions at [square root of]Snn = 2.76 TeV measured up to PT = 100 GeV/c with the CMS experiment at the Large Hadron Collider (LHC) are presented. In the transverse momentum range PT = 5-10 GeV/c, the charged particle yield in the most central PbPb collisions is suppressed by up to a factor of 7 compared to the pp yield scaled by the number of incoherent nucleon-nucleon collisions. At higher PT, this suppression is significantly reduced, approaching roughly a factor of 2 for particles with PT in the range PT = 40-100 GeV/c. A simple modeling of the parton energy loss applied to the PYTHIA Monte-Carlo (MC) reveals that the charged particle spectrum with the pQCD-motivated fractional parton energy loss can describes the shape of the measured suppression well in the range PT = 5-100 GeV/c.
