AbstractAbstract
[en] The present status of the experimental situation in neutral current interactions is reviewed. The basic properties of neutral currents have been investigated in four main fields: inclusive reactions, single pion production, elastic scattering from protons, and elastic scattering from electrons. New results presented at the Symposium are compared to those previously known. The properties of neutral currents are discussed in the light of all these results. Failure to observe neutral current with a corresponding strength in atomic transitions is discussed. Experiments are presented which are likely to solve this dilemma. (orig.)

Es wird ein Ueberblick ueber den aktuellen Stand der experimentellen Untersuchung der Wechselwirkungen des neutralen Stroms gegeben. Die grundlegenden Eigenschaften der neutralen Stroeme wurden in vier Hauptbereichen untersucht: inklusive Reaktionen, Produktion einzelner Pionen, elastische Streuung an Protonen und elastische Streuung an Elektronen. Neue, auf dem Symposium vorgestellte Daten werden mit bereits bekannten Daten verglichen. Die Eigenschaften der neutralen Stroeme werden im Licht all dieser Ergebnisse diskutiert. Die Tatsache, dass die neutralen Stroeme mit entsprechender Staerke in atomaren Uebergaengen bisher nicht beobachtet wurden, ist Gegenstand der Diskussion. Experimente werden angegeben, die moeglicherweise dieses Dilemma aufloesen. (orig.)Primary Subject

AbstractAbstract
[en] Two techniques are proposed to test the universality of the μ/minus/e weak neutral current interaction of large Q2. Both techniques require large statistics and some degree of longitudinal e+,e/sup minus/ polarization but are otherwise feasible at PEP

AbstractAbstract
[en] The measurement of weak neutral current processes allows a determination of the space-time structure and the isospin structure of these currents. The inclusive production data and the elastic neutrino electron scattering rules out a pure V or A structure of the current. A pure isoscalar current is in disagreement with the experimental data for the one pion production off neutrinos. Further aspects of the neutral current can be determined in neutrino-nucleus-scattering experiments. (BJ)
[de]
Die Messung von schwachen neutralen Stromreaktionen erlaubt eine Bestimmung der Raum-Zeit- und der Isospinstruktur des Stromes. Die Daten der inklusiven Streuung und die elastischen Elektron-Neutrino-Ereignisse schliessen eine reine V oder A-Struktur des Stromes aus. Ein reiner Isoskalarer Strom stimmt nicht ueberein mit den experimentellen Tatsachen der 1-Pion-Produktion durch Neutrinos. In Neutrino-Kern-Streuexperimenten koennen weitere Aspekte des neutralen Stromes gemessen werden. (BJ)Primary Subject

AbstractAbstract
[en] A brief historical review of the development of the mixing among quarks is given, i.e. the quark states contributing to the weak currents are mixtures of the quark mass eigenstates of strong interactions. The mixing matrix is discussed. Non-leptonic decays of the D meson are covered

AbstractAbstract
[en] Results are presented on the structure of the weak neutral current as derived from the ratios Rsup(ν) = (NC/CC)sup(ν), Rsup(antiν) = (NC/CC)sup(antiν), and the ratio (rsub(c)) of the total charged-current cross-sections. The total charged-current cross-sections are also given. The neutral-current coupling of the s quark is derived from unfolded distributions of (dσ/dy)sup(NC). These distributions are also used to set a limit of 3% on any scalar or pseudoscalar contributions to the weak neutral current
