A new version of the Casimir effect where the two plates conduct in specific, different, directions is considered. By direct functional integration the evaluation of the Casimir energy as a function of the angle between the conduction directions is reduced to quadratures. Other applications of the method and a magnetic Casimir variant are mentioned.
We present evidence that an interplay of the laws of microphysics and cosmology renders the Planck momentum unattainable by an elementary particle. Several categories of accelerators are analyzed and shown to fail.
Recent experimental searches for neutrino mass in tritium beta decay yield a negative value for the mass-squared of the electron neutrino. If this effect is genuine, then it is hard to understand it using conventional particle physics ideas as embodied in the standard model or its simple extensions that have been widely discussed. We consider the possibility that there is a hidden anomalous long range interaction of neutrinos that is responsible for this effect and study the phenomenological consistency of this idea. We also discuss how such interactions may arise in extensions of the standard model.
We propose a search strategy for the light R0 (glueballino) particle suggested by G.Farrar in connection with the light gluino scenario. The basic idea is to moderate and stop the R0 particles and then observe their decay to almost monochromatic pions - at an appropriate time delay relative to a primary collision event, where a gluino jet, likely to fragment into the R0, was produced. This technique is optimized at colliders and depends on qualitative features of the R0 hadronic interactions which we discuss in detail.
We study the effect of coherent and incoherent broadening on neutrino oscillations both in vacuum and in the presence of matter (the MSW effect). We show under very general assumptions that it is not possible to distinguish experimentally neutrinos produced in some region of space as wave packets from those produced in the same region of space as plane waves with the same energy distribution.
