Abstract

We describe the plans for and expected sensitivity of the HPW proton decay detector. Particular emphasis is placed on reconstruction and signal/ background studies. A brief discussion of future baryon number violation experiments concludes.

    The success of “SU(5)” depends on the success of SU(3) and SU(2) × U(l); for example: mHiggs? mW,Z? Generations mC, mb, mt? C-P violation? m and v oscillations? Desert? n electric dipole? confinement…? SU(5) monopoles? The successes in Reference 1 are, however, still of great encouragement.Google Scholar

    For example, P(n)2 ≈ n-5 where n is the muon multiplicity; n has been observed as high as 13/m in 1 μsec. deep underground. The Kolar events have been ascribed to neutral heavy leptons, background or other phenomena.Google Scholar
