If Be solar neutrinos can be observed in real time experiments, then an extended region of ∆m can be probed by a proper analysis of the rapidly changing phase of vacuum oscillations due to the eccentricity of the earth’s orbit about the sun. For the case of maximal vacuum mixing, a kind of Fourier analysis of expected data for one year’s time could uniquely pick out ∆m if it lies in the region ...

Motivated by the evidence for a finite neutrino mass we examine anew the interaction of neutrinos in a magnetic field. We present the rate for radiative scattering for both massless and massive neutrinos in the standard model and give the corresponding numerical estimates. We also consider the effects arising from a possible neutrino magnetic moment.

We review the status of hard interactions, in particular of jet and heavy flavor production , at HERA and LEP. Emphasis is given to recent theoretical developments. Instantons, event shapes, and prompt photons are also briefly discussed.
