The observation of underground muons from the direction of Cygnus X-3 during the January 1991 radio flare
Physics Letters B 269:1-2 (1991) 220-226
Abstract:
Muons recorded in the Soudan 2 underground nucleon decay detector from January 1989 to February 1991 have been examined for any correlation with the radio flares of Cygnus X-3 observed during this period. On two nearby days during the radio flare of January 1991 a total of 32 muons within 2.0° of the Cygnus X-3 direction were observed when 11.4 were expected. © 1991.Observation of the decay KL O→ e+e-ep+e-

Abstract:
Two events with the characteristic of the decay KLO→e+e-e- have been observed with a negligible expected background from which a branching ratio of (4±3)×10-8 is derived. This result is consistent with values estimated from theoretical models based on the double internal conventional of the decay KLO→γγ. © 1991.OBSERVATION OF THE DECAY K0L- E+E-E+E
