Experimental test of Baryon conservation: A new limit on the nucleon lifetime
The result of a search for nucleon decay using a 300-ton water Aerenkov detector located in the Homestake gold mine is reported. The nucleon total lifetime is found to be TN>3×1031B yr, where B is the model-dependent probability for production and detection of a decaying muon following a nucleon decay event. In the SU(5) grand unified model, published calculations of B vary from 5% to 10%, thereby yielding nucleon total lifetime limits in the range (1.5-3)×1030 yr. © 1981 The American Physical Society.
