High-energy physics at Tufts University. Final report

Technical Report · Fri Dec 31 04:00:00 EST 1982

OSTI ID:6421250

This Final Report summarizes research accomplished at Tufts University in High Energy Physics during the period 1957 to 1982, with emphasis on the period since 1979 when next previous such summary report was submitted. Activities and publications up to 31 December 1982 and not earlier reported are listed. Principal accomplishments during the past six years include: measurement of the near equality of the charmed D/sup 0/ and D/sup + -/ lifetimes; determination of important features of nu/sub ..mu../ cross sections on nucleons, of majority quark momentum distributions, of charmed ..lambda../sub c//sup +/ production and decay of quark and di-quark fragmentation, and of Z/sup 0/ left-handed couplings to u- and d-quarks; the second observation of the upsilon particle; the hadronic production of the J/psi particle via the chi charmonium state; observation of virtual-photon shadowing in deep-inelastic muon scattering; and observation of evidence for two new scalar meson states. In theoretical work, a detailed understanding of the nature of optimal representations of amplitudes and observables in scattering processes has been achieved.
