Search for Magnetic Monopoles, Neutrino Oscillations, and High Energy Particles: Progress Report, 1 February 1988-31 January 1989.

摘要

We have used the Homestake Surface Air Shower Array and deep Underground Scintillation Hodoscope to measure the composition of cosmic ray primaries above 100 TeV, measure the transverse momentum of hadron interaction secondaries produced by hadrons with energies of 10 sup 14 eV to 10 sup 17 eV, put limits on the flux of magnetic monopoles, fractionally charged particles, and muon producing neutral, low mass particles that reach the earth from various active stellar systems. We propose the use of the three existing air shower arrays in the western United States as a long base line multi-array system to search for sporadic bursts of ''gamma ray'' like emissions from Her X-1 and other binaries that contain a neutron star. Several observations in the past year suggest that either these high energy gamma rays undergo strong interactions in the atmosphere or that there are particle with gamma ray like properties that interact as hadrons. 10 refs., 28 figs., 1 tab.
