title = "Search for LNV/LFV K+ decays at the NA62 experiment at CERN",
abstract = "New results are presented for the first time of searches for lepton number violating (LNV) decays K+ → π−e+e+ and K+ → π−μ+μ+ from the NA62 experiment at CERN using a subset of 2017 data. No LNV signals are observed and upper limits are set on the branching ratios, B(K+ → π−e+e+) < 2.2 × 10−10 and B(K+ → π−μ+μ+) < 4.2 × 10−11, at 90\% confidence level.",
