AbstractAbstract
[en] We examine the single-particle formalism used to describe neutrino interactions. A null-plane quantization scheme is used. We set up the general formalism as well as some techniques needed to perform phenomenological calculations. The single-particle formalism developed by Wolfenstein is recovered at the cost of making several approximations, the validity of which is discussed. (author)

AbstractAbstract
[en] Direct and indirect evidence for the existence of a new heavy quark b and of new heavy neutral leptons N/sub e/ and N/sub μ/ can be sought in neutrino and e+e- scattering. These particles are expected to have right-handed currents. Discussion is given on the characteristics, production and decay of hadrons such as bb, ub and db, and of the massive neutral leptons. Muon number violation with and without N/sub e/ and N/sub μ/ is considered

AbstractAbstract
[en] This paper presents a proposal to extend the present Beijing Electron Positron Collider into a Tau Charm Factory. To achieve this aim the author points out that a number of things need to come together, and to be successfully communicated to the Chinese government. Such a machine is a logical extension of the present BEPC device. The physics which can be accomplished at such a device, is important, and cannot be duplicated in planned meson factories, due to the presence of resonances and thresholds which allow minimization of systematic errors. The author stresses the need for international coorperation on this project, to have hope of it coming to fruition. The whole concept of such a Tau Charm Factory needs more support from the high energy physics community

AbstractAbstract
[en] The VEPP-4M electron-positron collider is now operating with the KEDR detector for the experiment of precise measurement of tau-lepton mass. In this experiment, monitoring of beam energy spread is important to know the energy spread contribution into the total systematic error. Information about the energy spread gives an opportunity to reduce the error of the tau-lepton mass measurement. Several techniques for energy spread measurement are described in the paper. Width of the ψ' resonance measured with the KEDR detector is used as a reference

AbstractAbstract
[en] We present a general analysis of the effective potential for neutrino propagation in matter, assuming a generic set of Lorentz invariant non-derivative interactions. We find that in addition to the known vector and axial vector terms, in a polarized medium also tensor interactions can play an important role. We compute the effective potential arising from a tensor interaction. We show that the components of the tensor potential transverse to the direction of the neutrino propagation can induce a neutrino spin flip, similar to the one induced by a transverse magnetic field. copyright 1999 The American Physical Society

AbstractAbstract
[en] The major activities of the High Energy Physics Group at the Univ. of Maryland during the current contract period, that began five months ago, have been: construction and installation of modifications to PLUTO for 2γ physics, continued analyses of e+e- events taken by the PLUTO detector at PETRA, analyses of high energy neutrino-deuterium interactions from the Fermilab 15' bubble chamber run, final analysis of the ν/sub μ/e elastic scattering experiment at Fermilab, assembly and first test run of the hadron jet experiment at Fermilab, tests with the neutron dipole apparatus and new cold neutron source at Argonne, and participation in two major large proposals on e-p collider experiment at Fermilab or Brookhaven, and a neutrino detector facility at Los Alamos

AbstractAbstract
[en] Consequences of the weak selection rules for the new particles (charm, heavy leptons) are discussed for inclusive measurements. The quantities studied are ratios of mean numbers and of mean energies of π+ versus π-, K-bar0 versus K-, and K0 versus K+, both in e+e- annihilation and in ν and nu-bar reactions. For e+e- annihilation, we also give bounds on π+-energies in terms of the total energy available. The results hold with arbitrary cuts on π's and K's. Some results for e+e- annihilation do not require full lepton detection, others do. For neutrino reactions, we also give bounds on the total number of kaons in terms of the number of observed K/sub S/ → π+π-. Special care is taken to fully include the complications arising from the isospin-violating decays D* → D + π (or γ) and from the frequently occurring inseparability of production and decay mechanisms. Three main classes of events are considered, namely tagged decays in e+e- annihilation, single-fixed-sign-lepton production in e+e- annihilation, and prompt dilepton events in ν and nu-bar reactions
