Search for the Decay $K^0_L \to π^0 ν\barν$

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/200012We performed a search for the $K^0_L \to π^0 ν\barν$ decay at the KEK 12-GeV proton synchrotron. No candidate events were observed. An upper limit on the branching ratio for the decay was set to be $6.7 \times 10^{-8}$ at the 90% confidence level.4 Pages, 5 figures; Rev.2: replace figures 2 and 5, improve/add some sentencesHigh Energy Physics - ExperimentSearch for the Decay $K^0_L \to π^0 ν\barν$text
