An international collaboration reported the first major results from the experiment KOTO, which is being conducted at the Hadron Experimental Facility of Japan Proton Accelerator Research Complex (J-PARC). The KOTO collaboration set the upper limit of once in three hundred million on the rate of the neutral K-meson (kaon)#1 decay#2,3 into a neutral pi meson and a pair of neutrinos from the analysis of the data set collected in 2015,
