Search for lepton number violation and resonances in the $K^{\pm} \rightarrow \pi\mu\mu$ at the NA48/2 experiment
Thanks to a large sample of kaon decays collected in 2003-2004, the NA48/2 experiment at CERN is able to set an upper limit on the rate of the lepton number violating decay BR(K(±)→π (∓) μ(±)μ(±) )< 8.6 × 10(-11) at 90%CL, and to set limits at the 10(-10) — 10(-9) level on the appearance of reson...
