Abstract: | The nonobservation of photon-induced e+e? pairs pointing in the neutrino beam direction in large bubble chambers would allow one to set an upper limit on the product mνμλCM for muon-type neutrinos, where mνμ is the mass and λCM is the intrinsic partial decay width in sec?1 for νμ→γ+X. In the theory of Eliezer and Ross where , this implies an upper limit on mνμ considerably smaller than the present upper limit, and a large lower limit on the lifetime τνμ. |
